Tranny issue - 93 DeVille

[Mystar]

I have a problem with my transmission on a 1993 Cadillac Sedan DeVille. It keeps blowing a 10amp fuse on the firewall inside of the car. Repair man said it has to be a wire hanging causing it to short out. I have had it chaned 4 times now. Today it lasted only 1 hour before it blew again. Any suggestions on where we can look? I don't have another car to depend on while the repair guy starts the process of going through all the wires to find the right one. I would be ever so greatful for your help. I am also on a limited income which doesn't help much either.

Can you find out which fuse is blowing (what it is labeled or the fuse number in the fuse block)? That would help narrow it down - I am not familiar with fuses that feed the transmission.

Is it the fuse under the dash on the passenger side? If so, I think it also protects the AC circuit and the powersteering switch circuit (I think). The AC compressor could be going bad if it is that fuse. JUst a thought; maybe you could clarify which fuse it is. good luck.

I was thrown waaaaaaaaaay off by the title of this thread. When I hear tranny I can't help but think Van Buren Ave here in Phoenix.

LOL.. tranny on Van buren.. I lived in Scottsdale while I did my undergraduate studies at ASU for a yr. Thats all it took me before the heat got to me. I moved back to the midwest where its easier to get heat from a car than AC.....Its been 20yrs I am sure things have changed alot.

I've had the same problem. That fuse blows, and from a stop, the transmission feels like it's slipping terribly. ***The transmission and A/C clutch are both on that circuit. It is the A/C clutch worn out and slipping. I didn't believe that would cause too much cirrent through the fuse and blow it. I then manually jumpered the A/C clutch. I used an ammeter to measure the current. Normal current is approximately 5A, which I observed when the clutch was working properly. But when the clutch began to slip, it would climb as high as 20 amps. To verify for yourself in a simpler way, run the car all you want with the climate control set to ECON. Not long after you turn the system back to AUTO, using the A/C, the fuse will blow. Still investigating it this compressor clutch is sold as a complete unit with compressor, or separately.
