40 30le transmission

I have a 96 jeep Cherokee with a 40 30le transmission , what I need to know is there a way to turn the pressure up in it and if so how ?
 
It's solenoid-controlled, so not really. Disconnecting it will give you full line pressure all the time, but I cannot speak for the longetivity of the transmission if used that way for an extended duration.
 
How is this OPs first TB post? I get a XJ looks like a 740 a distance but this still doesn't seem like the right place to ask
 
Interesting, makes more sense although odd not to include background info for people who can't connect the dots (me)

I recall hearing 960s and automatic Supras shared a trans too, don't remember the generation but something to look into.

The Mk3 supra had a version of the same trans but it used a throttle valve cable for shifting pressures instead of a solenoid. The Mk4 supra used the exact same box as the 960, but with an extra 'buffer' solenoid on the pressure circuit IIRC. I have a Supra TT auto box in my garage that I was going to use on a previous whiteblock swap, but never got around to it. They're a bit tougher than the 960 box, which is actually no slouch itself if it's in good nick.
