7 speed automatic rebuild

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.

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??

WILD370Z

that was the problem i had they alot of people said if i did not floor it as much in 5-6-7th gear that was the nail in the coffin i also didnt know how to increase the line pressure with my up rev tune

Now we know why? So to hear that man, Your turner should have done that for you, I can even imagin how you drove the car with out the line pressue adjusted.
Is the dealer covering you Tranny? Or did I miss something. BTW your car look SUPER NICE

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.
