7 speed automatic rebuild

show2nite

I can't believe it AT tranny already experiencing slippage within a 2 year time fraME. Stories like this is what scares me to invest in a FI application.

all of mine was corrected with a line pressure adjustment.

1. So you're no longer experiencing (slippage/tranny problems)?


2. Was the FIX due to UPREV Adjusting the line pressure on your TQ management Table?


3. How you're experiencing higher Temperature, 200 Degrees, with a Transmission Cooler + Fan ? But yet a member 'ANMVQ' has only seen 185 Degrees

1.yes I have a tuning cable and log it and adjust it.

2.see 1.

3.I live in Georgia where it's hot even in winter.

Thank you for the responses, much appreciated Baer. I've 7 AT myself, which is why I asked you those questions. I'm highly interested in purchasing the GTM 1.5 SC KIT but a little nervous due to hearing stories about Transmission issue on the AT.

Baer383

The issues only show up,

1.flooring it in 5-6-7 gear
2.hole shots
3.hanging out at red line allot

I'm very hard on my car but it is still running very well,shifting good,no oil consumption,so I really can't complain.

How much miles on your Automatic Tran mission with the Turbo Setup?
Have you experienced any problems! Valpozguy???
How long have you had your Turbo Setup?

This can't be the first you've heard of this? It's widely known and highly disscused that the clutch plates in the higher gears can't take the higher torque. It's not a huge deal just part of the game and there are fixes for it. Tranns cooler, increased line pressure, upgraded valve body and fully built tanns.

I heard allot of the problems on the AT stems from trying to floor it within gear range 5-7 (OVERDRIVE). Reason the problem arises from those gears is that they are not as strong at that range because it main use is for OVer Drive. Correct me if I'm wrong.

2. ?? what is Hole Shots? Is that smashing on the GAS pedal at a stop light??

show2nite

I just though that the 7 AT Transmission was built Stronger than its predecessor, 5AT.....

Baer383

2.yep

And Kaien is right there are fixes for the problem

I mean when MT guys go high power they upgrade the tranns also right, same thing with the AT.

Me too, But a lot less WTRQ, Supercharger.. 7SPD auto car should be back at the dyno in 2 weeks.( I hope)



show2nite:: Hole shots are jammming from a gid( Flooring it from a stop). All the I did 7 back to back pulls at the track a month or so ago and tranny as fine..

Along with the UPREV TQ table managment A MUST -With out this I would be supprised if the tranny lasted 2 months,, An you also NEED a trans cooler, With out either of these the tranny WILL slip and break.. The UPREV at the very least as soon as you bolt the FI kit on,, The cooler could wait but not that long..

Thank you ANMVQ I see You know my Homie Squeeze!

I am going to be purchasing the GTM KIT 1.5 SC soon. I already possess a 28,000 BTU (Largest Tranny Cooler Size from my old setup). I have to order a good oil cooler though is their another reputable good brand besides Stillen?
