GM 700R 4WD AUTOMATIC REPLACING
GM TH350 4WD QUICK ADAPTER
This adapter kit is designed to be used for the 4WD 700R transmissions when trying to replace a GM TH350
4WD transmission. The TH350 had a approximate output shaft stick out of .875". The 700R output shaft stick
out is approximately 2.75". The 1.875" spacer takes the 700R shaft length down to the same as the TH350. Note,
some applications do require the end of the 700R shaft to be trimmed off which is the beveled portion of the shaft.
The 700R is 1.875" longer than the TH350 plus the spacer adapter of 1.875" so the new transmission length of the
700R with the 50-8505 kit installed will be 3.75" longer.
We have included new metric studs for the 700R transmission and a new T.V. cable will need to be installed for
the 700R transmission.
We do offer an option of a new output shaft for the 700R, 50-6900 which would eliminate this spacer adapter and
shorten your drivetrain 1.875".
