2. Stock Transmission Info T.L.C.

Land Cruiser vehicles were manufactured in numerous configurations, having thousands of different model classifications. These numerous classifications came about from the various countries that the Land Cruiser was exported to. This section of the manual mainly deals with Land Cruisers found here is the United States and some vehicle found in Canada. Some of the major differences between the different model classifications are the body types and stock engine options. For instant, the stock drivetrain on a FJ40 and a BJ40 are basically the same with reference to the transmission and transfer case; however, the F in FJ designates a gas in-line 6 cylinder engine and the B in BJ designates a diesel 4 cylinder engine. The information listed below was put together as accurate as possible. We recommend that you verify your drivetrain components and vehicle type before ordering conversion components. There are a couple of models that we have left out due to the low production number of these vehicles or if the vehicle model has not been a popular application for doing a conversion.

A. FJ25 (1958-59): This early Land Cruiser came equipped with a 4 speed transmission and a single speed transfer case. There are no adapters available for this model transmission or transfer case. The engine found in the FJ25 is the in-line 6 cylinder “F” motor. This vehicle looks like a FJ40 but it had no front turn signals on the fenders.

B. FJ40 (1960-63) (J30) 3 Speed Transmission: This transmission is very similar to the 3 speed found in the 1964-73 vehicles. This 3 speed transmission was normally shifted by a column shifter and was coupled to a 2 speed, 10 spline transfer case. This transmission is considered light duty. You should consider changing transmissions for added strength. If you wish to retain this 3 speed transmission, the column shift linkage must be changed out to a floor shift. The engine found in this FJ40 is an in-line 6 cylinder “F” motor.

C. FJ40 (1964-73) (J30) 3 Speed Transmission: This 3 speed transmission is 8-1/2” long and easy to adapt to both the Chevy and Ford V8 conversions. The input shaft size on this transmission is a metric 10 spline that will interchange with a standard Chevy 1-1/8" 10 spline clutch. The stock bellhousing indexed to the transmission by utilizing the front bearing retainer. The 1st gear ratio on this transmission is 2.7:1; 2nd 1.65:1, and a 3rd gear ratio of 1:1. The transmission output shaft coupled to a 10 spline, 2 speed transfer case. The engine found in this FJ40 is an in-line 6 cylinder “F” motor.

D. FJ40 (July,1974-80) (H42) 4 Speed Transmission: This transmission has a case length of 12”. This heavy-duty 4 speed transmission is capable of handling most V8 engines. The 1st gear ratio on this transmission is 3.5:1; 2nd 2.3.1; 3rd 1.4:1, and a 4th gear ratio of 1:1. The input shaft size on this transmission is a metric 10 spline that will interchange with a standard Chevy 1-1/8" 10 spline clutch. The stock bellhousing used two dowel pins for alignment to the stock transmission. This Toyota transmission is equipped with a 16 spline output shaft which coupled to a 2 speed transfer case with a 16 spline input. The engine found in this FJ40 is an in-line 6 cylinder “F” motor in 1974, and then switched to a 2F in-line 6 cylinder from late 1974 to 1980.

E. FJ40 (August 1980-83/84) (H42) 4 Speed Transmission: This transmission is very similar to the previous 4 speed transmission listed above except that a 19 spline output shaft was used in the transfer case. The Land Cruiser got an upgraded heavy-duty transfer case which was nicknamed the split-case. The gear ratios remained the same as the previous 4 speed. This transmission/transfer case combination did not use bellhousing mounts, but now used a crossmember support that bolted to the transmission case. The engine found in this FJ40 is an in-line 6 cylinder 2F engine.

F. FJ45 (1963-67) J30 3 Speed Transmission: This 3 speed transmission is 8-1/2” long and easily adapted to both the Chevy and Ford V8 conversions. The input shaft size on this transmission is a metric 10 spline that will interchange with a standard Chevy 1-1/8" 10 spline clutch. The stock bellhousing indexed to the transmission by utilizing the front bearing retainer. The 1st gear ratio on this transmission is 2.7:1; 2nd 1.65:1, and a 3rd gear ratio of 1:1. The transmission output shaft coupled to a 10 spline, 2 speed transfer case. The engine found in this FJ40 is an in-line 6 cylinder “F” motor. The FJ45 is the pickup version on the Land Cruiser. There were various truck bed lengths on the FJ45 which were designated by a letter after the “5” in this vehicle. These various models of the FJ45 can all be treated the same with reference to the drivetrain.

G. FJ55 (1968-73) J30 3 Speed Transmission: This 3 speed transmission is 8-1/2” long and easily adapted to both the Chevy and Ford V8 conversions. The input shaft size on this transmission is a metric 10 spline that will interchange with a standard Chevy 1-1/8" 10 spline clutch. The stock bellhousing indexed to the transmission by utilizing the front bearing retainer. The 1st gear ratio on this transmission is 2.7:1; 2nd 1.65:1, and a 3rd gear ratio of 1:1. The transmission output shaft coupled to a 10 spline, 2 speed transfer case. The engine found in this FJ55 is a in-line 6 cylinder “F” motor. The FJ55 is the early station wagon version on the Land Cruiser. H. FJ55 (July,1974-80) (H42) 4 Speed Transmission: This transmission has a case length of 12”. This heavy-duty 4 speed transmission is capable of handling most V8 engines. The 1st gear ratio on this transmission is 3.5:1; 2nd 2.3.1; 3rd 1.4:1, and a 4th gear ratio of 1:1. The input shaft size on this transmission is a metric 10 spline that will interchange with a standard Chevy 1-1/8" 10 spline clutch. The stock bellhousing used two dowel pins for alignment to the stock transmission. This Toyota transmission is equipped with a 16 spline output shaft which coupled to a 2 speed transfer case with a 16 spline input. The engine found in this FJ55 is an in-line 6 cylinder “F” motor in 1974, and then switched to a 2F in-line 6 cylinder from late 1974 to 1980. The FJ55 is the early station wagon version on the Land Cruiser.

I. FJ60 (1980-84) (H42) 4 Speed Transmission: This transmission is identical to the 1980-84 FJ40 4 speed transmission listed previously. This transmission has a 19 spline output shaft to the transfer case. The Land Cruiser got an upgraded heavy-duty transfer case which was nicknamed the split-case. The gear ratios remained the same as the previous 4 speeds. This transmission/transfer case combination did not use bellhousing mounts, but now used a crossmember support that bolted to the transmission case. The engine found in this FJ60 is an in-line 6 cylinder 2F engine. The FJ60 has a square body with 2 pair of round headlights.

J. FJ60 (1985-87) (H42 Long) 4 Speed Transmission: This transmission is identical to the 1980-84 FJ60 4 speed transmission listed previously. This transmission has a 19 spline output shaft to the transfer case. This 4 speed used a 3-1/2” factory spacer adapter housing between the transmission and transfer case. This was to simplify the production, keeping the 4 speed the same length as the 5 speed transmission found in the FJ60s overseas. The transmission gear ratios are the same as the shorter version H42 transmission. This split transfer case had the cluster pin diameter upgraded to 38mm. This transmission/transfer case combination did not use bellhousing mounts, but used a crossmember support that bolted to the transmission case. The engine found in this FJ60 is an in-line 6 cylinder 3F engine. The FJ60 has a square body with 2 pair of round headlights.

K. FJ60 (1985-87) (A440F & A440L) 4 Speed Automatic Transmission: This transmission was the first automatic used in Land Cruisers. The transfer case that coupled to this transmission was still the split-case 19 spline unit. This split transfer case also had the cluster pin diameter upgraded to 38mm. This transmission/transfer case combination did not use bellhousing mounts, but used a crossmember support that bolted to the transmission case. The engine found in this FJ60 is an in-line 6 cylinder 3F engine. To convert this vehicle and retain the automatic, the stock engine must be the 3F. The transfer case adapters we offer for the split transfer case all fit this transfer case; however, be aware of crossmember support considerations. The stock crossmember may have to be modified or a new one fabricated to support your new transmission. The FJ60 has a square body with 2 pair of round headlights.

L. FJ62 (1988-90) (A440F & A440L) 4 Speed Automatic Transmission: This is the same transmission used in the FJ60s. The transfer case that coupled to this transmission was still the split-case 19 spline unit. This transmission/transfer case combination did not use bellhousing mounts, but used a crossmember support that bolted to the transmission case. The engine found in this FJ62 is an in-line 6 cylinder 3F-EFI (electronic fuel injected) engine. To convert this vehicle and retain the automatic, the stock engine must have been the 3F with or without the EFI. The transfer case adapters we offer for the split transfer case all fit this transfer case; however, be aware of your crossmember support. The stock crossmember may have to be modified or a new one fabricated to support your new transmission. The FJ62 has a square body with 2 pair of rectangular headlights.

M. Imported 5 Speeds 1983 & up (H55F): These transmissions are only used in Australia and Japan, but we've also seen a few come out of Canada. Some of the specialty Land Cruiser companies also import these 5 speeds. This transmission is found in both the FJ60 and FJ62 Land Cruisers. This transmission looks identical to the long H42 transmission. This transmission has a good 1st gear ratio of 4.84:1, and an overdrive ratio of 16 percent. These transmissions are a great upgrade for FJ60s originally equipped with a long H42 4 speed transmission. The adapters we manufacture for the 4 speed will also work the same on this H55F 5 speed.

NOTE: Land Cruisers that were originally equipped with a diesel engine have a longer input shaft. These vehicles were called BJs (if the Land Cruiser had a 4 cylinder diesel) and HJs (if the Land Cruiser had a 6 cylinder diesel). Transmissions that were previously equipped to a diesel engine will require the installation of a new input shaft. The input shaft from a gas version transmission with the same tranny code is your best choice. We can also special order bellhousing adapters from Mark's 4WD that are designed for the diesel engine replacements and would not require an input shaft swap. The BJ and HJ transfer case applications match the FJs for the most part.

SPECIAL NOTE: Vehicles (Nov. 1984 & Up) equipped with a 3F engine had a transmission bolt pattern that was rotated clockwise 7 degrees. This was done to improve front driveshaft clearance. The stock transfer case was also rotated accordingly and was usually fitted with a vacuum operated shift linkage. When using one of our bellhousing adapters or Ranger Torque Splitter on vehicles originally equipped with a 3F engine, this rotation will cause installation difficulties.

N. FJ80 (1990-92) 4 Speed Automatic Transmission (A440F or A440L): This transmission was found coupled to the 3F-EFI engine. The transfer case in this vehicle was changed to a full time 4WD model (HF2A). The FJ80 had an option of a 5 speed transfer case and a part time transfer case; however, these were only found in non-U.S. vehicles. The bellhousing adapter for this automatic is available from us through Mark's 4WD of Australia. This adapter couples the automatic to the Chevy V8 and retains the transmission in the stock location. The only consideration is that this transmission is computer controlled. Besides the bellhousing adapter, you will also require a tachometer interface kit and also retain the throttle position sensor from the stock engine.

If you plan on replacing the stock automatic transmission with one of the GM transmission adapters, we only offer the adapter to replace the stock automatic transmission. This adapter allows the transfer case to remain in the stock location and the crossmember is the same position. If you have a FJ80 replacing a 5 speed, driveshaft modifications will be required because this transmission was a different length than that of the automatic. We can also special order adapters with the correct adapter length for vehicles replacing the 5 speeds. Toyota updated the square body style to a rounded body with the FJ80 models.

O. FZJ80 (1993-97) 4 Speed Automatic Transmission (A442F): This transmission was found coupled to the new 4.5L 6 cylinder engine. The automatic transmission in these vehicles was still coupled to the new full time transfer case (HF2A). The FZJ80 had an option of a 5 speed transfer case and a part time transfer case; however, these were only found in non-U.S. vehicles. There is no bellhousing adapter for this automatic as of yet.

To convert this vehicle, you must replace the stock automatic transmission with one of the GM transmission adapters. We only offer the adapter replacing the stock automatic transmission. This adapter allows for the transfer case to remain in the stock location and the crossmember is the same position. If you have a FJ80 replacing a 5 speed, driveshaft modifications will be required because this transmission was a different length than that of the automatic. We can also special order adapters with the correct adapter length for vehicles replacing the 5 speeds. The FZJ80 was still the rounded body style.

P. 100 SERIES (1998-07) 4 Speed Automatic Transmission (A442F): This transmission was found coupled to the new 4.5L 6 cylinder engine. The automatic transmission in these vehicles is still coupled to the new full-time transfer case (HF2A). The Series 100 Land Cruiser had an option of a 5 speed transfer case and a part time transfer case; however, these were only found in non-U.S. vehicles. There is no bellhousing adapter for this automatic as of yet.

To convert this vehicle, you must replace the stock automatic transmission with one of the GM transmission adapters. We only offer the adapter replacing the stock automatic transmission. This adapter allows the transfer case to remain in the stock location and the crossmember is the same position. If you have a Series 100 replacing a 5 speed, driveshaft modifications will be required because this transmission was a different length than that of the automatic. We can also special order adapters with the correct adapter length for vehicle.
