I've actually been doing some research on this lately.. I've actually found several numbers that folks say are the TCC for our cars. Maybe someone can clear it up..

The most common GM part number I've found 8634960 and then there is 8639900 and 8639956 Also I hear you can use one for a 700R4 trans. You have to shim it a little. It's a "beefed up" one for the 200R4 but I have'nt found a GM number for that either. Funny part is turbo Buick guys from all over have used all of the GM part numbers I listed and they all seem to work :confused:

Where are the trans pro's! :D

thanks for replying so have you actually changed yours? if so wich part # did you use?
 
I bought one from Kirban's Performance and swapped mine out... It was an AC Delco part and works fine... Their site doesnt say the part number though and the wrapper/ old solenoid are 200 miles away at my parents house in missouri :(

Yes he does and it's also $20 bucks more then the one from GM Parts direct. I'm pretty sure the one I ordered was 8634960 I'll have to dig thru my papers
 
gmpartsdirect.com said part number 8639900 for 46.92 shipped to your door unless your in N.C which has to add sales tax. but check for yur self.
