Auto or Manual Trans. Did you remove the torque converter nuts.

Remove both drive axles first. Remove started.. remove transmission blots and torque convertor bolts. remove engine mounts. Support the engine with another jack to keep it level. 2 or 3 hours to do by yourselt...Good Luck!!!

IF YOU REMOVE ALL SIDE MOUNT BOLTS AND TRANSMISSION MOUNT BOLTS REMOVE SHIFT AND RELAY SHAFT RODS IF EVERYTHING BEEN REMOVED AND DISCONNECTED TRY PRYING TRANSMISSION AWAY FROM ENGINE.DO IT EASY NOT HARD TRANSMISSION COULD BE CAUGHT ON SOMETHING.

you better have alot of special tools needed for this job,your holding the engine in from up on top,and removing the carriage from the bottom that hold the engine and transmission up,let alone removing the axles.

At the top of the transmission where the hydraulic clutch cylinder rod is attached, you have to remove the lever from the shaft (14mm nut), because the clutch is the 'PULL' type pressure plate bearing system. After you remove the trans, you will need to remove the bearing from the pressure plate and put it back on the input shaft collar in the trans before reinstalling the trans.

Sounds to be the front pump seal on the trans. Yes, the seal can be replaced but the trans must come out, engine stays.. Remove the torque converter with the trans. and make sure they are properly coupled when reinstalling. Good Luck Ned. I Live in Mira Loma if you neeed coacjhing.

remove crossmember, axles, cables, tranny mount bolts (3), tranny to engine of course bolts
