The tranny on my truck is nearly dead. The deciding factor of weather I'm going to fix it is the overall health of the engine of my truck. Since I bought it used, I have no way of knowing what condition the engine is in, but it seems to be running pretty good.

What steps are involved in testing the compression and what is a good range for the results? Harbor freight has the tool fairly cheap.

harbor freight has a diesel compression tester? you cant put a tester designed for gas engines up to the task of a ctd.
gas motors are around 150psi. the diesel is several hundred psi. the gasser model will explode.
but if its a diesel version, pull the injectors, ensure the shutoff solenoid doesnt get energized, and crank away.

Thanks for the reply. I meant to post this under 24v engine but accidentally posted here. Anyone want to move this?

you only need 2 or 3 revolutions to get your pressures. most of the time you can tell by the blowby if you dont have tons of blowby you more than likely are good on compression
