ok...i know people who turbo their automatic hondas always bitch that the tranny always the first thing that give up. Anyway, I was thinking that tranny should be fine as long as you don't launch it form a dead stop. i'm planning to install a turbo in an automatic civic (as test bunny) and i like to see the good/bad about it..

I'm about to turbo my auto accord. My friend has the same setup with a build motor/turbo/nitrous and still on the stock auto tranny. The only problem he has is that it slips when it's cold. If it slips get it rebuilt with a level 10 PTS kit.

 

i had a t3 turbo on my wife's auto integra ls at about 8psi for around 2 years.we sold the car last friday with 129,000 miles and the tranny never gave us any trouble

 

75 shot of unheated (proper bottle pressure) nitrous made my buddy's 2001 accord lx tranny start sucking it up.

2nd gear slips pretty badlyand the shift time is abotu a full "1 mississippi + 1/2 second" vs the stock .8-1 or so seconds

well, this car will prolly never see track time. i just want to get a little power out of it (to get in and out of the traffic).

Have had mine boosted for abot 5k now and it runs really well....you just need to get in the habit of letting off before the shift under normal driving conditions.

 

ya,
i have a 2000 ex coupe AUTO with greddy turbo

just make sure to let off the throttle before car shifts to let the tranny easily do it...
otherwise no problems

 

i am confused. If you turbo a automatic how do you see large power gains when the transmission shifts much lower than running the gears out manually? I am not trying to jack the thread, but i had been thinking about this the other day and I could not figure it out.

 

I've ran Nitrous and then 10psi of boost on my tranny and i've had no problems with slipping. I think the real problem with the tranny's is because of the heat, some people don't upgrade to a larger tranny cooler. Also Alot of problems i believe with tranny failure is manual shifting it.

The AT only shifts lower when your not in boost or not pushing it. When im in boost or pushing it, the transmission won't shift until i let off the throttle a little or till it hits redline. I've had no problems with My car being auto and boosting because it can build boost off the line and hold boost while it shifts gears. Although I am in the process of swapping in a GSR tranny just because i prefer manual and its less expensive than building the AT

 

Here's a quick in-car vid of my car from a standstill, nothing too special but gives you an idea of how the car shifts at WOT.
