First of all let me start with some background info 10-50 miles before this incident two things happened. First one, I had electrical issue with my car (blowing engine control fuse) ,after a lot of struggle and a visit to an electrician, the electrician decided to cut a blue wire going down to the transmission. I'd later notice the overdrive switch isn't working anymore after checking the manual I think the wire leads to the overdrive solenoid.
I drove it a few miles after that.
Second thing that happened, the car was overheating and radiator water was boiling. As the radiator was clogged I changed it. No more issues from this side. (However when I unmounted the radiator no oil came out of the transmission cooler is it normal?)
My zj is a 1993 awd 5.2l

What happens is when the car will move when I give little to no gas, it changes gears normally, gets into reverse,neutral,drive.. no noise whatsoever. It happened out of the blue while I was going uphill.

I think I said it all, if anyone have a clue of what is happening i'd be infinitely grateful.
Thanks in advance.

Did you check the trans fluid level?

Your "electrician" is a hack. It is embarassingly inappropriate to just cut wires for the heck of it without actually repairing the fault. I hope you didn't pay him much.

Your transmission needs some love. When was it last maintained?

forgot to mention I did check my transmission, two odd things. First, although it looked fine it did smell burnt.Second the previous it seems to be overfilled, the previous owner that is a friend of mine is pretty sure he did not overfill it.

Well, if it make you feel better i didn't pay him yet, and don't plan on doing so. maintenance as in fluid change? less than a year ago as mentioned before not by me though. Do you have any idea what could cause the short? (it is a pretty strong short)

Transmission basic maintenance on these: fluid & filter change, front & rear band adjustment. If those are not done when they should be, expect seeing physical transmission failure at around 150-200k miles.


Fuses blow for two reasons: there is a short, or a component/ components in the circuit is/ are drawing too many amps.
Use the factory service manual (FSM) wiring diagrams, measure each wire with a multimeter possibly affected, and check the wire harnesses for cut wires & rubbing between body/ components.
