I was wondering if anybody had figured out how too raise the line preassure in the auto trany to get firmer shifts. I heard that some how you can go into the tranny ECU and remove or add some resistors somewhere to increase the line pressure. Anybody heard of anything like this, or am i just outta my mind?

our line pressure is not controlled by the ECU. get a custom valve body made for it, you'll love it.

any idea where a guy could look to get one made?

If you adjust the kickdown cable it raises the line pressure. Look at your manual or the online one It says to adjust it to 1mm. I set mine 2 to 3mm and had a lot better shifts.

When you raise the pressure you also raise the temp of the fluid. Spend the 60 or so $ and get another cooler or your tranny will be toast soon.

I toasted mine...jacking up line pressure...but it was fun...burned out at every shift......well i can always find newer trannys mine had 170k on it....got one with 65k for 200bux

Also run royal purpel tranny fluid...your tranny will like you

David_rg79............how did u raise the line pressure, by adjusting the kickdown, cable or a different way, i m just trying to explore my options.

When me and my dad rebuilt mine...we upped the line pressure with some valve body customization....thats about the only other option

You can keep it cool with a 93 4RUNNER 4x4 tranny pan, holds 2-2.5 more fluid. 100 bux from the dealer.
