Slips in low, But the trans brake holds??? With the trans brake on you can bring the rpms up and the car doesn't move? Who's servo did you use ?

Is this a new build, or was it a working trans before, i kinda curious, doesn't that valve body require some holes drill in the case. I'm not a trans guru, but do rebuild my own once they have been built by a trans specialest.

Zip.

You might want to check your converter and pump.

You need to check some pressures. Did the trans just start doing this or is this a fresh/rebuilt trans? The T-brake only applies Rev. with 1st gear slipping the car should back up. Checks pressure at the servo cover and at the reverse tap (if you have one). Post your results. You can give me a call at the shop to 727-375-4737 Matt
Also if this trans just start to do this, I have had a few hipster aluminum brake have the bolts come loose.

On your band adjustment, are tighting it to 72inch pounds then backing off 3-4 turns?
