Retail Price: $189.40

Advance Adapters

The GM 700R4 main shaft kit is generally used when replacing a TH350. Once installed into the 700R4, the output side of the 700R4 looks identical to a 4WD TH350 that is being replaced. The adapter kit includes a new output shaft, plastic washer, o-ring, and metric fastening hardware.

The one piece GM 700R4 output shaft used in this kit is made out of 4340 alloy steel. This output shaft is manufactured with the highest quality materials and standards as the OEM output shaft.

This main shaft kit can also be used with the 4L60 and 4L60E overdrive automatic transmissions.

I ordered an output shaft for a 2wd 700r4 transmission in order to convert it from 2 to 4wd. Advance Adapters came through in flying colors and the price was reasonable as well. THANKS
