quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

i think this is a little late to be thinking about it... but it never really crossed my mind...

im trying to boost an automatic transmission... has this ever been done without redoing the transmission or the torque convertor or anything like that? will boosting my car kill the transmission?

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

auto trans works on a set of valving. you can buy shift kits for any transmission that will beef up your auto trans vavling. i don't know where or who sells that sort of thing though

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

B&M makes shift kits I think I am turboing my auto teg right now

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

be sure to get an external tranny cooler..

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

are these parts necessary? i havnt found any info on these topics yet.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

any ideas? anyone?

im only gonna boost about 6-7 psi. im not trying to race just want a little more go... will this kill my tranny?

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

do it and find out! people have boosted auto trannys before on hondas. We are just giving you suggestions, most people here dont have them, so they really dont know what to say. If I was doing it, I would definatly get a external tranny cooler, because HEAT kills auto trannys.

do it and find out?! that sounds really risky to me...external tranny cooler? what exactly is that?

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

A external tranny cooler mounts in front of your radiator, tranny fluid goes through this cooler and cools down when it enters the tranny. Stock ones are located inside of the radiator, you would just need to relocate the lines.

Try it and find out? risky? lol, what else have you got to loose man? everybody is throwing custom turbos on their cars on this website... gotta grow some balls sooner or later. Dont think you will be the first kid with a turbo automatic honda, because people have done them before, and they do work.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

its like a radiator for your transmission fluid

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

naw i dont think id be the first AUTO TURBO... im just saying im scared to do this cuz my knowledge of cars is so limited. id like to turbo my car but im scared ill really blow something up.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

i have an automatic too... the transmission doesnt seem to play a huge roll in the grand scheme, just slap a transmission temp guage on the dash and make sure its ok

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

you got an auto and you turboed it? do you have pics of your setup and stuff? im so anxious about turboing my car but im freakin scared too...

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

well i jsut got finished watching a turbo automatic IS300 video and he is running well over 400Hp at the wheels. I know he has a torque converter and prolly more but it can work.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

Would it be better to just reroute away from the radiator/tranny cooler and just use the external cooler? OR to add the external tranny cooler inline to the radiator's cooler? And would there be a pressure issue with adding the external cooler inline?

"well i jsut got finished watching a turbo automatic IS300 video and he is running well over 400Hp at the wheels. I know he has a torque converter and prolly more but it can work. "

right, i know it can work... but im just wondering if im not pushing like crazy amounts of boost do i need an external tranny cooler and/or a torque converter...you know stuff like that.

im just trying to figure out for my application.. do i need to do any kind of tranny modifications to run 7psi of boost.
but thanx for the info...

and that girl with the red shirt is FREAKIN HOT!

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

Tranny cooler:
I've got the Econ-O-Kool made by imperial.
Mine goes into the radiator first then into the new cooler then back to the tranny.
Here's some shots from when I installed mine
Installed:

Kinda hard to tell but the right hose is the fluid return hose.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

do you have pics or info on the install. i dont think it would be TOO HARD but more pics are always helpful. from the pics you gave me its kinda hard to see where you tapped from the radiator and where the outlet of the tranny cooler goes to...

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

I'm not familiar with hondas but when it comes to jbodies the auto trannys can handle more HP than the manuals. If you tranny is electronic look into a B&M ShiftPlus, if its not then get a shift kit for it. It may not be necessary but it will give it a sportier feel by shifting harder and wearing your bands in the transmission less.

As for the cooler you probably dont have to have that either. Althought its a very good idea to install one. Like Jeff said heat kills trannys...and so does the slippage in the bands. The more HP you run the more they will slip
between shifts and wear unless you improve that like i stated before.

So do you have to do anything besides the requirements of the turbo setup...NO... but if you want it to last you have to invest in some protection.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

hey, pick a day, get under your car, and look at it, just visuallize where everything should go. Check out the cooler that is already installed, once you know what you can work with, find some parts, then get to the technical stuff

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

As Jeff said...Grow some balls.
You learn from your mistakes.
Well smart people learn from other's mistakes, but there isn't a lot of people her with an Auto tranny.
So you would have to ...Just Do it. ;D
Look at your budget and try to do as advised before.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

i dont know... maybe its just me... but doing something like this without research and preparation is hardly called GROWING BALLS. that just sounds like STUPIDITY. im just trying to get some info so i dont seriously mess something up. if im here in the first place it means i have some intention of turboing my car. dang... wassup with all this flamin... its been a LONG FREAKIN DAY!!!

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

They haven't even begun flaming.

I wouldn't suggest throwing a turbo on your auto tranny. The Honda auto trannies are.....well, they are junk. IMO of course. They weren't meant to handle any sort of performance driving. You will go through trannies like I go through clutches. I can buy a clutch for allot cheaper than you can buy a tranny for.

As for the "j bodies" and big blocks, those transmissions were built to handle the power of a high torque 8 cylinder engine. Honda does not have a high torque engine. Hell, Honda doesn't even have a mid torque engine :P

If you want your transmission to last, put a cooler on it, get a temperature guage for it, and keep clean fluid in it. Hopefully it will outlast my clutch ;)

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

thank you...for saying something that is helpful. ive already started looking into a tranny cooler. ill be sure to add that to my list. thanks for the heads up.

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

Dr. Boost,

I wasnt sure if the honda trannies were good or not since I have not owned one. But as for the high torque v-8's in jbodies... Jbodies are cavaliers and sunfires mainly. Our 2.4's do happen to have quite a bit of torque for a 4 cylendar though.

I know its not fast compared to some of you guys but we have auto's running mid 13's with nitrous. We just upgrade to the B&M shiftplus or auto trans interceptor since our 4speeds are electronically controlled.

Either way I will be putting a tranny cooler on my car even without a turbo setup....it will drastically prolong the life of even a stock trans.

Thanks for clearing that up though dr boost... like i said I know very little about honda's so I didnt want to say "yeah sure it will be fine" lol

Re:quick question...CAN AUTO TRANSMISSION HANDLE BOOST
 

Hahaha, I was thinking about old Mustangs and Camaros and Chargers!!! ;D I wasn't familiar with the term "J bodies". lol

I have seen Auto Honda's with Nitrous that performed well, and were plenty fast. I would recommend a transmission cooler for any car. It's cheap insurance and an extra saftey measure.

You can't compare auto trannies for performance driving vs a manual. We(auto drivers) know that we can't launch at 4-6k RPM and can't do some of the other "neat stuff" like burnouts and hard downshifting(without consequences anyway) that manual cars can. But it goes the same for manual cars too, if you dropped your clutch at 4-6k RPM all the time and shifted at 6k each time, how long would your manual tranny last? It's all about how you drive and maintain it. Manual vs Auto, reminds me of Domestics vs Imports ::)
The Auto trannies should do fine as long as you don't abuse it like already mentioned. And get an external tranny cooler, it's a very cheap insurance and less heat is always good.
