M22 ID
 

Hello everybody....I need some help with a ID on a M22. The numbers are as follows:
Case-- 3925661
Tail-- 3978764
Side-- 3952648
Input- 3915020
ID # CC1 35238 or 88 can't tell
What is it out of? I was told a Buick...from what I can see it's a 1971.

Re: M22 ID
 

CC1 35238 or 88 is the part # for a replacement case (1 main case in a box bought over the parts counter)... 661 case was used 2nd half of 1970 thru the 1974 model year... the 1 in the CC1 means it went into the parts system in 1971... The CC designation started with CC9 thru CC4 I have examples of all... The CT designation denotes a complete transmision assembly, also CT9 thru CT4... 1968 and older complete transmisions have just a P number date code without a VIN...
Without the number of grooves around the input or tooth counts of the big end of the cluster and the input gear can't tell if its a M-20 or 21 or 22... Hope this helps... Crash

It's a 26 spline input with a fine spline output...like a Turbo 400. So this trans is a replacement trans...ie. not out of a Camaro or Chevelle originally? Where did you find this information....is there a website I could refrence?
Thanks for your help.
