Just curious, I did a little searching but really could not come up with anything.. I have really been looking into trading my auto for a manual only because I remember reading a thread where Tibby03 posted and said that the stock auto tranny went out at like 250wtq.. Is this true? I also read a stock auto tranny could hold like 400+whp.... So I am not sure exactly which is correct, I have a completely stock auto tib, and sometimes when I am flooring it and the car trys to shift, it "slips" like its trying to grab the gear but slips off it and I get a loud clunk each time it trys.. Max trys was like 3 before it got into gear... It doesnt happen all the time and I am taking it in on next Friday to try an get it fixed under warranty.. Does anybody know any similair cases? And can someone answer my max hp/tq question for the tranny? Thanks a lot!

^ That may be true, but what does that have to do with his auto tran's horsepower limit question!?! :3_confuse

have your tranny checked under warranty..

the auto tranny is a stout little bugger. i know of at least 2 tibs that are running around 300whp on the stock auto and no problems... the manual (6 speed especially) is the one that needs help... you would need a performance clutch at the least..

are you slipping in 2nd to 3rd? if so it is common. it happened to me a lot, but it seemed to stop after I put some ground wires on (they haven't been on to long, so it just may be a cowinsadence(sp?))

as to max hp/tq, every car will have different reactions to mods, so I guess 300ish seems to be the average

if your going to mod, mod it all. not just engine

It happens whit my Tyb too, from second to third. If i go sraight down the road its ok ,but when i go down the hill it happens.

If I'm not mistaken ..I do Believe Chris(MinesBetter)hes' pushin 250 Whp+ and the only mod he has to the trans is the converter and a Posi ?..Not Positve tho and they say he has a nasty good launch with it.......and Tibby03 is running well over 300 + With some minor mods and Stall in his auto and there gonna push well past that(400 ? ) with his new set up.......realistically the trans is capable of handling 250 Hp all day and that is alot of go ponies

Tibby03 has a custom built race tranny by tc from NGM, correct me if Im wrong...

I have been wondering the same thing for close to a year now. Since most of you guys are more experienced, what steps should us beginers take in modifying to keep our auto transmissions in one peice? I was gonna trade my tibby for a wrx, but all my buddys told me to stick with the tib. They all said to swap out my trans for a built 3 speed, but that sounds very pricey. My friend owns Strictly Modified in Schaumberg, IL, for any one from chicago, and I'm gonna go get their opinion. Any insight and advice would be appreciated. Thanks guys.

Theres no built 3 speed. The only built transmission is offered by nextgen, however I dont think tim is ready to release it just yet. The autos though are good past 300whp just from what i seen in dynos and minesbetter tib. However alot of people have mentioned that a torque conventor is well worth the investment.

I will definitly look into a torque converter. Hopefully that LSD will be ready soon, because I would defenitly love to get my hands on one of those. Also maybe a transmission cooler, I've heard those help a great deal.

You know you play MMO's too long when you see the phrase MAX HP and you wonder for a moment how many Hitpoints the auto Tranny can be buffed to...

/sigh... ah well. i got a laugh out of it. i am sure other readers who can relate will as well.

Hahaha, that's classic. I haven't played an MMO in quite a while, but I know that I've read things like that before.

I think its speedfreak that has a lsd, its just hard has hell to find a tranny shop will to install one on a fwd auto. A tranny cooler helps also, but I wouldnt worry about this unless you go f/i

I looked up speed freaks LSD and its for the manual only. i know that an auto one is in the process of being made. is there a shift kit available for the auto trans that i can buy?
