I have a donor car lined up for my T5 swap but I need to know for sure. We're all T5s mated to V8s in 1989 World Class T5s. The donor car is an 89 GTA 5.0 TPI 5-speed. I'de hate to spend the $500 and then find out the tranny isn't WC.

 

IIRC, the WC first appeared in 88, so you should be fine unless, of course, the tranny isn't original to the car. There may be a metal date tag attached to the case. Also, on the left side there's a 50 Torx bolt (the non-WC has a 21 mm 6-point)

That stupid PIT team / ISO9000 / Total Quality Mgmt / etc. 80s buzzword is really just B-W's lame excuse for a way to say "verion 2" or "2nd design".

They made the new design available starting in about 86, and GM stayed with the old design transmissions for a short while and then switched over to buying the new kind in 88.

I just posted some pics I found showing the difference between the 1st design and the 2nd design YESTERDAY. Can't be more than 5 or 10 posts earlier than yours. Reading other people's posts where they ask the same question, especially an extremely redundant one like this one, is always a good idea, even if the Search feature is broken.

Here's a link to the pics. You can see this part even while the transmission is still in the car.
