I have a 1994 Jeep Grand Cherokee/180-hp, 4.0-liter I-6.
I have been having the worst luck with it. It has electrolysis that goes through the radiator. So I have an extra grounding cable on the engine to help prevent me from going through to many radiators. I still have to replace it every now and then.
The real problem is my transmission, I have replaced it 2 times in the past year. I just put in another one a week ago. The mechanic said he couldn't fix the problem and said it was an electrical problem most likely a bad ground. The Jeep is drive-able but it cant shift properly at all.
I would like to try and find the problem myself, but I just need to know where to start.
