98 Ford Escort ZX2 Alternator Question

Right now I believe my car is having transmission issues. I'm starting with poor circulation of the transmission fluid. My question today however is as follows:

Is there anything in this area (transmission) or related that could severally shorten the lifespan of an alternator? Run the alternator out or wear it out faster than normal?

My car will hit about 5,000rpm around 30mph a few minutes after starting it.
Popping the car into drive (D) from over-drive usually brings the rpms down and then popping it back into over-drive will set the car right and it feels as if it shifts properly, sets in to place and drives somewhat normally. Overall though the car has a hard time accelerating, hesitates to shift gears, and feels as though it's just working too hard to travel at 30+mph.

I just put a new alternator in it seeing as the previous one died and I'm worried about this new alternator. Any help or info would be greatly appreciated.

Are you having trouble with the replacement alternator?

the tranny has nothing to do with the alternator.

no the new alternator is fine
that's what I was looking for
even if the tranny is not directly involved could any form of stress from anything in the engine wear the alternator out fast?

No, the alternator supplies power. It's the first link in the electrical chain when the motor is running. The only time I have seen an alternator in trouble because of an engine problem was on an old Chevy that had the alternator at the bottom of the block, oil was leaking on it. Otherwise, don't worry.

Might check out the cat converter. It wouldnt cause alt problems (as they are usually each as durable as the next) but could be the cause of your performance and shift related problems. Other problems could be a dirty MAF, a bad temp sensor or o2 sensor, or a vac leak among other things. Even if the engine light isnt on a good computer diagnostic might possibly reflect problems the cars computer might not know about, like inacurate sensors and poor tuneup conditions (air/oil/fuel filters and plugs/wires) or a bad PCV valve or PCV hose assembly.

Good luck. If you cant get it figured out take it and have it looked at so you dont mess up something major. Usually its between $40.00 - $80.00 to get a diagnosis done, and in some cases they will do the diagnostic for free if you are paying them for parts and labor.

As for the question can the engine cause an ALT to fail, usually it just has to do with how many circles the alt in question has spun, but i suppose if you ran your car at +5000 RPM all day long it might cause extra heat and excessive wear.
