Have a 1994 jeep grand cherokee with transmission oil leaking between engine and transmission and making squealing noise was shifting fine before this happened all at once it quite. could it be pump and torque converter seal

check for a loose heat sheild on exhaust system usually on top of catalytic converter....happened to me

I'm having a problem with my tranny not wanting to shift automatically at all. Seems like a dead stop its stuck in low gear. Have to manually shift and does not go into overdrive. I have a 1993 Jeep Grand Cherokee. Can anyone help me cause I've swiched out throttle control sensor, filter change, new tranny cooler and heavy duty lines. I'm at a loss and scratching my head. Any advice would be greatly appreciated

Sounds like the rear main oil seal on your motor is leaking. In order for it to be replaced, the transmission has to be removed. Not an easy task for the backyard mechanic.

Very likely it's the rear seal. You will have to remove the transmission from the jeep in order to gain access to and change that seal.

remove gearbox from engine and then flywheel and then change crankshaft oil seal, not a job for the faint hearted. Could the oil be dripping down from the camshaft cover, this is more common and easier to sort

Check the Trans fluid level with it running and at operating temperature. Jeep NAG1 transmissions are known to have the input electric seal leak trans fluid. Not an exspensive fix add Mopar ATF4 and then relace the guild seal.

Check transmission fluid level, then look at transmission linkage. Some are in a place where they can be bumped around and knocked out of place. Tweek the shifter a little on both sides of the resting position when you shift. If the noise goes away. It is probably linkage related. If you can sample the tranny fluid, check for burnt smell and or metal flakes. Aamco will check it free but dont let them sell you repairs as preventative measures. They will try.

Check both connections to make sure they are tight. Look carefully to see if fluid is coming from the fitting or where the nipple comes out of the radiator...If leaking there it usually can be fixed by any decent radiator shop.

check all hose that have tranmission fluid. don't forget the one that on the radiator.

First of all make sure you are checking the fluid right. Some people do not know that in order to check transmission fluid the engine needs to be running and the temperature needs to be sort of warm althought you should be able to get a good Idea just by the engine running. In this instance you might have a governer valve that isn't properly working to shift the engine when hydraulic pressure reaches a certain PSI. I would suggest having it flushed and put in new fluid and filter. If this doesn't work the problem is more serious and might need some professional assistance.
