Tranny problems caused by too many amps being drawn???

[Pekin21]

A friend of mine had his ATX tranny go on him and took it to a shop. They rebuilt it and said part of the damage to the tranny was caused by his sound system (dual 12" with a large amps - can't remember how big). Has anyone heard of this before? I haven't and the only thing I could think of is the current draw messes with the processor? Maybe making the tranny not shift correctly?

Thanks!

Something about that doesn't sound quite right. The only processor that the car has controls both the tranny and engine control.

That's what I thought, anyone else have an opinion?

The only thing I could say is that it takes a certian amount of current to pull in the shift selinoids. If that current is not available the selinoids will either not pull in or take too much time to pull in. This may cause some slipping in the transmission. However, the selinoids get there current from the computer and if there was a problem there would be a code in the computer. Besides, I would think that the alternator would have sufficient current capabillity to drive all loads on the car. If not you would see the light dim.

I agree, sounds like the shop is blowing smoke.

My old Avenger (automatic) would shift kinda funny when you were slowing to a stop as it went back through the gears, if you had alot of accessories on.
However..I dont remember what year (93 maybe? it would cover all ATXs then), all SHOs came with like 130 amp alternators. That should be enough current to cover ALOT of stuff.

That is interesting....I was starting to wonder if the corroded, broken positive battery wire in my car was causing the computer to go all funny and cause sloppy shifting....
