I have a strange coolant leak between the automatic transmission and the engine on my 89GXE. I have several manuals that all suggest removing the engine and transmission as a unit and then separate the two. I would prefer not to do that and would like to drop the transmission by itself so I can determine where this leak is coming from. I know I would need to support the engine before dropping the tranmission. Does anyone know of a different fix? Of course I would prefer not dropping the transmission if I can repair this leak without doing so. It is however a bad leak and a stop leak product is definitely not an option. Any ideas?

 

What do you mean by strange? Do you see coolant on the ground or does it just seem to disappear? If you can see coolant on the ground..you can most likely trace the leak to the source. If you can't see any coolant on the ground, but yet you ocassionaly run low on antifreeze then you might be burning it.

 

Possible a leaking freeze between the engine and tranny.
There are three freeze between E & T
If so you have to remove the tranny.

 

To remove the tranny you DO NOT need to remove the engine also. I read the manuals for my tranny replacement, and it said to remove them as a unit, but later I was talking to my mechanic and he says that they do them all the time without remove them as a unit. Several people on here also told me that it can be done without removing both. It saves a ton of time to just take the tranny out, there's much less connections, and you don't have to have an engine hoist.

 

Thanks for the all the helpful info.

Sudesh - what I called a leak was more like a gusher. The leak was strange because I could not trace the source.

ninezero - I didn't know there were any freeze plugs behind the flywheel so that's probably the source of my problem.

davis4005 - I thought it was possible to drop the tranny by itself but the manuals seemed to suggest there was some reason not to.

I worked as a lineman for an electric utility for about 13 years before taking another position. Going on 18 years total. If I can ever help with any electrical questions, I will do my best to assist. Thanks

 

I figured that it could too, but both the Haynes, and Chilton's manuals say that it needs to be removed as a unit. I had to do my t-belt and studs anyways so it worked out fine. Good luck on finding that leak, and let us know how it goes pulling the tranny.

 

I changed the three freeze plugs and removed for this only the
