I have a 98 auto LS and I plan on swapping the tranny sometime down the line but not anytime soon. Im curious to know (IF I BOOST) whats a safe amount of psi I ran run without hurting the tranny. Someone told me like 3-4 pounds. I just wanna know if thats true.

 

I've seen a turbo CB7 run 13's that was an automatic.. Not exactly sure if there was any mods to the tranny but i know he was makin over 200WHP

 

im not sure if the b-series auto is weaker or stronger then the d-series , so i can only talk about my old d-series auto. i had a d-series auto trans and i ran mine with up to 13lb of boost for a long time. before i had a turbo i was running a 75 shot of nitrous for over 25 bottles.

it had 100k miles when i converted to a 5 speed but i sold it. the new owner of my old auto transmission says its working perfectly.

tip: use honda auto trans fluid and change it often.

Holy crap 13lb on a stock D Trans ? Which trans and what motor was it on. and did you get the trans new or used before you installed spray?

BTW don't use psi as a reference, use power. psi is meaningless unless there was only one turbo ever made.</TD></TR></TABLE>

Funny you talk about the trans lasting on those who dont launch hard often. I had those same thoughts, but never really looked into it further. I also think thats the reason why mine lasted. the frequent honda atf fluid changes im sure helped some as well.

well i never went to the dyno on my t3 setup. it was a t3-60trim on 13psi. go ahead and guess what whp that was on a d16y7. i would have to guess around 160whp for the auto trans..
