right. there is 13 pressure points on this transmission. if you sit on seat check port 1 is under your right heel on the transmission this is system presure ,should be about 180 psi.check port 2 is about 3 -4 inches to the left of port1. this is torque convertor pressure should be about 120 psi. then try port 3 which is a comman port for clutch pressure. 3 is slap bang in the middle of the control valve ,it should read about 135 psi. try these 3 first i think you,ll find something here. make sure it,s warmed up and take readings at 3/4 of full engine speed. oil is j20a/c

that would be great! thanks! He also asked what type of transmission fluid and where is the pressure test port.

thanks again

time for a pressure test then, i,ll look up the settings tomorrow. my money is on torque convertor pressure

He checked the oil, and the linkage is ok.

Ok, my guy says while the unit is in drive and you accelerate at a high RPM, the unit will not move until about a minute or two and then it slowly goes into gear and takes off. He said it wasn't the u-joint.

did you check the ujoint?

firstly have you checked the oil , with the engine at tickover. then check linkage is ok ,sometimes the locking nuts on the rods come loose and lengthen the rods.

It is lever control. It does not drop out of gear. Any thoughts?

is your truck lever control or monotrol pedal. is it jerking like it,s dropping out of gear. check inching linkage is ok
