Engine/Transmission (1998.5 - 2002) Line Pressure

[lukesdiesel]

I had my transmission rebuilt about 3 months ago. In the next few weeks im going to install a Transgo Shift Kit. I also want to turn my line pressure up a little. What is a good Line Pressure for a good built transmission? I am looking for a very firm shift and I want strong lock up.

Who did the tras? Was it a custom build, or a stock rebuild? When upping the line pressure, if you go to far (without the resistor installed), the trans will go into limp mode. The different seperator plates, springs, orfices and what not make a difference.



How firm the shifts are, isn't all in the pressure. How the VB is otherwise setup has an effect as well. IIRC, mine is up ~180psi on the top-end. The way Dave sets up his VB, all depends on what you are plannig to do with the truck, and how it is used.



Since the PCM "learns" how you drive, it will firm up the shifts if you tow or drive with a heavy foot. If you drive with a somewhat light foot, or not towing, it will soften them up. Makes a difference if you manually shift the trans as well. The more you do, the firmer they are.

I am looking at installing the Transgo Shift Kit SK-TFOD Diesel. I am curious on what my line pressure should be when the install is complete. My truck is used mostly for everyday driving with some towing. I want performance more than anything. Are there any tips you can give me while im installing the Transgo kit?

I installed the same kit and just a bit of advise. I turned the pr screw in 3 turns and that gave me 152 lbs line pressure. This works well for my application which is similar to yours.

Other than that the instructions were pretty straight forward and no real surprises. Make sure you install the resistor. I tried it without and once you hit the freeway you will go into limp mode.....

What exactly is the snow plow option on the Transgo Kit?
