Hey, can you hold first gear with your 80, i'm trying to figure out why mine shifts into second on it's own even though i have it in first. There is another thread goin on that has this debate on it. Cause on my 60, i did the transgo and i could hold 1st after that, but as i recall i had a W4M tuned installed after that and i told them about the shift kit. But if you 0 out your part throttle shift mph, i don't think that would do anything, and i looked at my old 60 file and not much is different, nothing out of the ordinary was changed.

Actually 1Slowhoe, you are subscribed on that thread. Anyway, let me know.

 

I havent tried. Im about to go to baseball practice with my son. I will see what it does.

 

Yah let me know. I know you have EFI, but i actualy just tried changing my WOT mph in perf mode really high and it still shifts into second on its own. I think it's in the part throttle % table, i'll have to scale that up and see how that does, that's gotta be it though.

 

I have a shift kit in mine. I put it in 1st and I was able to hold first all the way to 4Krpm and I let out. It would have shifted by then for sure because I was only giving it 20% throttle.

 

Do you have a transgo in it? Cause i think that's the reason why i can't because i have a Superior Shift kit. Although i've really come to like it cause it's so tame normally but once you romp on it, man it shifts great.

 

Thats what I was told, Transgo HD2

 

I have the TransGo instructions on how to do the plate if you need it I can post it up , as gmforlife said the valve body is right under the pan and the plate under that , a new plate is only 25 bucks , some 80Es had aluminum plates , and most will switch that out to the steel plate .
