Oil leak
 
Took my jeep first time really off road and half way thru the trail had black oil dipping off the back of the trans. Mount. I can see some oil on the side of the trans. Just before where it flairs out before the transfer case. Any ideas where it would be coming from and how hard of a fix? It's am I6 5 speed.

Need to find exactly where it's coming from!

Drain plug, fill plug, reverse switch, and vent cap are possibilities.. Need to look around to see exactly where it is coming from.

Thanks...my plan of action is to degrease and clean everything Monday and maybe I'll be able to find the source.

I cleaned and let dry...still could not tell exactly were it was coming from so I started top down until I started feeling oil. What I found were four loose (I could turn them with my fingers) bolts at the top just under where the stick shift goes up into the cab. Would this cause a leak? Is it common for them to come loose?

Should/could I use locktight on them?

A common source for a hard-to-find leak is the engine's rear main seal. My previous '97 TJ developed a leak there.

I doubt your leak is coming from the top of the transmission, I would not use Locktite on those particular bolts.

Is the reverse switch on a 5 speed a black cylinder on drivers side mid-transmission? I have a little.oil around it and want to replace the gasket before I change fluids.

Is it possibe for the trans. to leak in the front where it meets the engine (where the rear main on the engine is)? If so, how much would a job like that cost to have someone fix?

Yes, that is where the reverse light switch is located & is the only component on the transmission with an electrical connector. There is no gasket there, it seals via an o-ring on the switch where it seats into the transmission.

It is possible for the transmission to leak from either the front or rear seal, but I'm still thinking the leak you're describing is more likely the rear main seal which can be replaced without removing the transmission.

Thanks for the follow up...the thing that got me thinking about the trans. Is that I replaced the fluid because I didn't know if the PO had ever done it and it was very low but I guess that could have just been from neglect.

Might be having a similar problem with my rear main seal leaking. Noticed a few drip spots, crawled under to confirm. Replacing the seal shouldn't be a big job since Jerry mentioned the transmission needs not be removed?

Sub'd for more info...

He mentioned black oil dripping. Transmission fluid should be red. Can recently changed transmission fluid get dirty enough to turn black? It takes my motor oil quite a long time to get dirty enough to be brown.

RevCo666 08-06-2013 07:19 PM

Gonna make an appointment with the jeep doctor tomorrow and see what they say :( I'm in between being either rear main seal or the leak is coming valve gasket cover. I'm actually hoping its the cover being my issue.

Auto trans oil is red but mine is a manual.
