88 Jeep Cherokee Transmission Fluid Leak

I have a 1988 Jeep Cherokee with a problem. It likes to leak transmission fluid. The other day I blew out a transmission cooling line. Replaced it, and even though everything appeared smug and no leaking, as soon as I started driving the Jeep it started leaking, almost gushing out of the Radiator, which on my Jeep was also the Transmission Cooler. I started the process of installing a brand new out of the box Transmission Oil Cooler. I followed the instructions perfectly, and still was having a leak. Everything again was leak free until I started it up and added transmission fluid. Where am I going wrong? I spent over 12 hours and about 150 bucks in parts/tools for the conversion. It is an 1988 XJ with the 4.0L I6 and AT. Any help would be greatly appreciated.

    I am using 5/16" transmission cooler hose. As for clamps just using the clamps that you have to screw down, the name of them are slipping me right now. Right now it appears to be leaking from the fittings that go to the new transmission cooler. I have tightened them as tight as I could by hand, didn't have a wrench handy. The only thing I could think of was that the fittings weren't going 100 percent into the hose, but then again they wouldn't fully fit in there. It isn't splitting the hose that I could see and it wasn't blowing off the connections.

    Yeah I think one of my problems was that I was getting the hose clamps on as tight as possible, I will be working on it again tomorrow and try that Would it also be helpful if i double clamp the hose ends that go onto the actually metal lines that run to the transmission?

You need to tighten those fittings with a wrench... if they still leak... remove them and wrap them with a couple turns of "teflon tape" the kind they use for plumbing. the clamps you should use are hose clamps of the same type that you use for radiator hoses... you will note these can be tightened with a socket.... you really don't need to over tighten them but fairly snug... transmission fluid has quite alot of pressure.

    if it's not leaking from there you need not bother.... if you do it tho... make sure that the part that is tightened... is not in the same spot as the other clamp.. in other words stagger them abit...

Why is gearbox oil getting into rhe radiator on my jeep grand cherokee 2003


it is probably not gearbox oil. it is probably transmission fluid because it travels through the radiator cooling tanks. the cooling tanks may have a leak causeing the fluids to leak into the radiator.

Jeep was overheating, Now leaking transmision fluid and won't start


I don't see how leaking transmission fluid would be connected to the engine overheating, unless the radiator blew up.
You'll need to figure out why it won't start to proceed.
Check for spark and fuel pressure, and of course compression.
Is the check engine light on ?

Yes it is a problem, you can have a waterpump that leaks as the engine runs, when the vehicle warms up coolant expands and goes to the resovoir,as you turn the engine off and the engine cools off the fluid in the resovoir reutns to the engine but here the problem the radiator cap cant do its job when the water pump leaks

My automatic transmission shifts hard,slips and sometimes overdrive dont work ,other times its perfect. i put 1/ 2 qts.of fluid per week but has no apparent leak


Are you checking the fluid in neutral? You need to be.You need to pull codes.The leak is most likely the transmission cooler line at the radiator end.

HI, this is just a pan seal that as failed to do its job due to age or defective nature. Once this faulty pan gasket is changed, the leak will stop.

Transmission fluid leak


Transmissions can leak anywhere there is a seal, fitting or gasket. Most common leaks are at the trans pan gasket and fittings.. However, to find a leak the only way is to get under there and look. A mid sized leak will clean off road debris and leave a track. Keep in mind that all leaks run down and that while driving this can be blown towards the rear of the vehicle. If you find a suspicious area, clean it off with a rag & some solvent and run vehicle...watch that area for seepage. Also check cooling lines to radiator. Fluid coming from inside bellhousing indicates a bad front seal (requires trans removal to repair) Fluid should be (for aw4 units) Mercon, or any quality synthetic that covers mercon application.
