Advance Adapters GM 700R4/4L60E Tranny to GM NP205 T-Case Adapter Kit

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.

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