Just got done putting my transmission together. I had a local torque converter company build me up a torque converter....

I'll be damned if the thing wont go on. It goes on two clicks and then after 2 hours of fightin it I gave up.

Are the input shafts different or somethin?

 

yes, the spline count is different.

 

gah......this suckkss

Anyone know if a th350 has the same splines as a early 4l60e? i have a broke 350 i can take apart to check the fitment with.

 

The splines are actually both 30. The LS style 4L60E is 6.5" tall. The old school 4L60/700R4 is 5.9" tall. Hope this helps.

This makes no sense then...!!! Grr I don't understand why im having so much trouble.

Need to find someone else around here to try so I know if im losing my mind or not.

 

Take a picture of the converter and of the trans input shaft. I can tell you what is wrong.

Chris thank you.

I got a new stall that worked. but it looks like im pulling the transmission out if its not a tune issue. having all sorts of problems. 2-3 flare/no 3rd upshift. 1-2 overrev
