Auto tranny problems with boost

[boostneeded]

I have a auto and i was minutes away from ordering the Dezod kit for autos but i have heard nothing but "your tranny will be gone in 3 months" all kinds of negatives. Does any body have REAL info and background on this?

The automatic trans in the tC is not a performer by any stretch of the imagination. It was built with 17 year old girls in mind; simple and easy to drive. Some have tried to alter the valve body but have run into many problems and no gain in performance since it is computer controlled. There are people out there with turbo autos. There just have to keep their power levels down to prevent damage.

Well the great thing is, this is my wifes so she just wants a little extra ummmfff me personally i think if i am going to spend the money on a turbo i really want to be knocked into the back of my seat. so i have heard that 5-6 psi would be a safe bet for the auto. And i dont ever see anyone on these forums that have meet and greats club rides. Is anyone from the south MS, LA, AL?

Navylife, are you active duty? i am in the navy as well. i am assuming you are from the east coast by some of the posts. im in MS active duty fresh from deployment from afgan which is why i am doing the performance upgrades now.

I am Stationed at NAS New Orleans. I recently got back from Detachment to Bahrain. I was not too far away from you. I went into Pakistan, said howdy, and left. If you ever see a 'Don't Mess With Texas' sticker, that was me either there or was some cargo that I hauled. I was Active till 2008 when I went back to the Reserves which I pretty much do full time. Are you in Gulfport with the Seabees?

As for the PSI, you should be able to get up to 7PSI on a DD auto with no worries.

[boostneeded]

Thanks for the info. Yeah im with the Seabees in Gulfport. We should meet up sometime, i dont know many ppl with scions.

[navylife59]

There are a couple of clubs here that meet every now and then. Yes, we should meet up sometime. Isn't there a 1/4 mile track near you?

[boostneeded]

Yeah there is a 1/4 mile track here and a lot of the guys are wanting to head out there and do a few runs before they start doing major upgrades but they arent Scions i hang out with a guy with a 3000gt vr4 and a guy with a Civic.(about to be turbo) and of course im about to get my turbo. What do you run anyway because from your pics you have alot alot done and your car looks really good man. Well talk to you later

[navylife59]

I run zilch as she has never been on a track. I should be running high 13's but with my stock clutch slipping under the pressure and no LSD it would probably be low-mid 14's. The stock clutch (new condition) handles up to about 230WHP or 200ftlbs tq adequately. Beyond that, you are overloading the clutch.

I deploy on a short Detachment May 12-28 then deploy on my family vacation for the summer. We should be rolling down the I-10 sometime towards the end of June. Would have to swing by for a pit stop there in Gulfport.

i have a ballbearing turbo its a sweet s i love it im pushing 339 with a built auto trans but with a stock you better stay under 240 hp or the tranny will go out other then that your good

[mauricet]

i have an built auto trans and im at turbo 339hp the highest you can go on a stock tranny is 240 trust me i know i hang out with the guy at ptunning cause i live down the street from there and ive see some auto tc tring to get more and when the do with out building it there back 3 mouths later with a tow truck so id keep it under 240

[navylife59]

The slush box does not seem to be able to handle the power. What was done to beef up your trans? It has been an unfortunate reality that there has been no rebuild kit with stronger parts for the masses to resolve the dilemma.

[univision]

If you guys know how to rebuild automatic transmissions, buddadamn, that's impressive!
Anyone know where I would be able to get replacement synchonizers down the road? My 2nd gear is starting to show the first signs of being weaker than the rest. Might have to replace it at 150k-175k along with a new gear.

[navylife59]

You are talking about the synchros in the gear grinder then. Myself, have been looking for a shop that can race prep my spare trans but no luck so far. Looks like it might just be OEM replacement parts.

i had better torque converter the one from the xrs colrolla serious pump work done allso better gears most parts came from a 2010-2011 colrolla and last you need a good autotrans cooler a good size one if you going over 300hp ptuning help out a lot with the project as of right now it still a project car that i drive ever day but just has a lot more hp but you better has cash in hand i spent almost 3000 doing this i might sell it soon cause i now have a 5speed trans im building up and about to drop in
