The hopes and dreams question.. Flame away

[superflysr20]

Hey guys.... I just feel stupid asking this and I will find out anyways as I have to replace the part in question... HOWEVER!!

I Have a 93 auto that yes is being readied for summer swap fun including a manual conversion but in the meantime would like to have a working spare car as a just incase

The tranny is shifting and engaging fine when I turn the car on and about 5 mins after any type of driving will start to feel like its slipping and won't shift up gears... If I turn the car off for a min and back on it will work again for a few mins

The alternator is bad which I realized yesterday after I couldn't keep it started
So my question is...

Could a failing alternator cause electrical issues that somehow effects Ecu logic to the tranny sensors causing it to miss shift? Basically can I replace the alternator and magically have a working car and ponys and rainbows and shit??

Again flame away i know this is dumb but just wanted to have someone crush my dreams before I build up what if excitement while I wait for an alternator (if anybody has one for a ka get at me

The auto is known to have the symptoms you are describing. Change to a new alternator and see if that fixes your problem....that is really the only choice you have at diagnosing this thing. how do you know you have a bad alternator?

I bad alternator shouldn't trip the automatic transmission ECU. At least I've never heard of such a case. Since your car works fine at start up, I'm guessing it's a temperature issue.

Either way, you should fix the alternator now.

When was the last time you changed the tranny fluid and/or filter?
