Ive seen a few videos of them. I did a search on it found nothing. Just curious as to any auto j bodies rolling around with turbos? How does the trans hold up? Any issues with the turbo?
I want to get the Hahn kit but they told me my tranny wont last? I have a Yank converter for it wating to be put in when the wether gets nice just incase theres any complications I will have another car to drive in the mean time. Also will do a trans cooler.
So whos got a Auto Turbo/SC j body out there?

It's a super investment for modified automatic cars. They actually help with the lifespan of the transmission. Get one.

I've read many places, and this makes sense, that due to less slipping of the clutches (the friction when shifting normally) it actually will help your transmission live longer.

I think hes referring to the Converter.
For some reason I was thinking he was talking about the Auto Trans Interceptor and how it works for turbo cars. Ok nevermind, I need to go to bed.

I have an S/C'ed auto J and no problems yet and I'm not expecting any. You should be just fine running either a turbo or an s/c. The tranny (specifically mine, which is the 4T40E) holds up quite well and can handle a good amount of power. Smart idea running the tranny cooler, it'll help preserve the life of your tranny. I plan on doing that as soon as the snow clears in the spring.
I've read that Hahn doesn't recommend using their setup on auto trannies because they believe that it can't handle the power. I'm sure you'll be fine in running their kit but I don't know if it will be a direct bolt on. Not sure what kind of car you have (Fill out your Profile!!) but on the Ecotec engine their kit will work but the IC pipes have to be redone. Just make sure you take precautions with your tranny like tranny cooler (which you have), synthetic tranny fluid (many prefer Royal Purple), etc.

Id like to try the Hahn Kit on my car. Id for sure be willing to get the piping made. It would be a sleeper for sure around here. No one has a turboed j-body.
Is the trans interceptor like a must have for auto cars?

No, it has nothing to do with power. Their piping does not clear the automatic transmissions, which is why they advertise for manual only.

Well then I'm curious as to what someone should be worried about when it comes to boosting with an auto tranny. I figured the power would cause an intense amount of pressure on and higher temperatures in the tranny causing it to wear prematurely. I'm always learning so I hope you can post up an explanation at least for me and for the author if it will benefit him.

According to someone who IM'd me, Hahn broke 3 auto trannies before they gave up. I don't see how Hahn breaks auto trannies, but other people were doing just fine on other company's setups (such as Jtuners)

I heard something like that as well. My best guess is that without maintaining your tranny with a cooler and the right fluid it can go to $@#! real fast. So its not power, its how the tranny is treated and modded with respect to other mods. Abe, you make me answer my own questions with statements that aren't direct but still to the point..you are a lyrical fiend.

i ran my 2.4 auto for a year on 10lbs of boost and it held up just fine...

uhh.... thanks, i guess lol. 
And anyone who wants to boost an auto should know that a tranny cooler is almost mandatory.

i have the automatic 4 speed, im running the gm supercharger (6psi) and a 40 shot of nitrous and my trans has never slipped one time at all and my cars got 64000 miles on it which is about to be 00000 soon but thats besides the point. i heard the autotrans interceptor and b&m shiftplus works fine but then if you take it off the tranny will slip. so im not so sure about them working good since they do that when you take them off. wish someone made a racing tranny for us.
well i dont recommend a B&M shiftplus. I honestly think that messed up my trans. I had mine for almost a year now, and just today i took it into the dealership because of the upshifts were slipping like crazy and i was getting very eractic shifting. I think the shiftplus just puts way to much line pressure and destroys the trans. Hopefully GM will fix my trans for me under my warranty. I removed the shiftplus before i took it in. BUt i also have the smaller pulley and pacesetter header... so we will see. After wards i think i might try the Autotrans because you can control the line pressure better. The shiftplus just seems like 100% and 200% increase.
The shiftplus also caused irratic shifting problems. The trans wouldnt stay in a gear, it would bounce around in the gears or could have been the TQ converter locking up. But i could be driving at like 45MPH, RPMS at like 2000 then it would just jump to 2500 and back to 2000. Speed wouldnt change, but i could hear and feel the RPMS change as well as see them.
SO hopefully the 2,000 dollar warranty i bought will fix this. . .it better. But i do not recommend the B&M shiftplus for our cars. Im selling mine now.

well I have a 3 speed automatic and between shifts it has a delay like no other. Now.. I have been told as well that you can buy a shift kit and will eliminate the delay and prolong the life of the trans... is that true as well?? because I'm just shy of buying a kit. I know though for a fact that it will eliminate the delay but as far as tranny life I'm not sure.
**changes are here**
Thanks for that clarification, Bill. I guess I can see what you mean and I really hope you get something out there for the auto folks (I'll be lining up to buy if you do).
Blown.
You can ask me in late January when my Turbo setup will finally be installed.

Supercharged cars that use a GM reflash have a distinct edge...the slippy upshifts have already been improved in the new program flash. Hate to admit it, but auto J's should go supercharged if only for this reason, at least until we all get this turbo-auto angle better sorted out!
can you explain to me why a reflash would help the trans from slipping?

It can pull out a bunch of timing just before the shift point to lower the stress on the trans during the shift.

Does it actually pull timing tho? Lets say you go turbo and use the GM Reflash would that help a lot not only with tuning by also the Shift?
Thanx Charles
