Early TCC Lockup (21ish mph)
I have a 86 305 tpi, 700R4 with 93,300 miles on it.
The TCC is engaging at 21 mph, and from what I've heard, that's not really a good thing, plus it bogs my car down and it feels like i'm running over a bunch of bumps, it'll shudder.
After reading a post on this site, about the 3rd gen 86 bugged prom I went and purchased a prom with the part number of 1228291 which is supposed to be the corrected one right?? So the TCC won't engage until 41 mph or so. Well I Installed it and it didn't change anything. Still engaging around 21 mph. Here are a few videos showing the problem.
This video is with very light accerlation.

This video is with moderate accerlation up to 30 mph, and then easing off, so it can shift, it shifts really sparatically I think?

Also, about the prom, in the article ( 3rd° Tech Tips~TSB~Bugged PROM ) It state that the 1228291 prom should have a date marking of 8646 or higher, the 1228291 that I ordered has a marking of 8612....how is that possible?
