Stall when put in Drive

When i got the car the alternator had gone bad and fried varistors in a few different things as well as the tcu. A friend of mine soldered new ones in, and i replaced the alternator with a higher output one and did the "Big 3".

Problem I'm facing now is when you put it in drive it stalls out completely, it will go in reverse though...

I'm not sure what exactly would cause this...
I did try using another TCU that i grabbed from a junk yard, but that didn't make a difference. It is possible that a component could have fried in the ECU? I did grab an ECU as well but didn't have time to switch it out, or open it up and check it out. There are also no CEL's being thrown either.

Anyone know what the cause of the stalling may be?

Thanks,
Joe

i didn't have any alternator or resistor frying problems with my first pearly , i used to shift fine then one day started shifting very harsh , then stalled out at the bottom of a driveway , started again and parked and from then on it would stall in any "gear". P and N it would idle fine but when i moved it to any gear it would just grab and stall

i was told it could be something inside the box or the torque converter had disintegrated internally . my dad (30yrs+)mechanic pulled it apart to see if he could find anything that would make it stall , he found nothing wrong with it at all

i was then told it could possibly just be the "b" solenoid not working
which im guessing controls the amount of slip the torque converter uses , in which case if its that , it wont slip at all causing the stall

Re: Stall when put in Drive

does it stall if you have all 4 wheels off the ground? you may be able to find out if it's not allowing slip (possible torque converter lockup solenoid) by shifting it into drive with your foot off the brake.

I did not think of that, I will try it out.
Problem is I don't have access to it everyday. I just moved from Maine to newhampshire, and left the car at a friends in Maine

Well trying to ignore, the over voltage burn up, I would try unplugging the plug on the left side of the trans, to turn off all the electrics to the box, so that it will only start in 3rd, and see if it still does the same thing.

I doubt it is the torque converter as it will go in reverse.

I will deff try that this weekend.
I hope its not the TC, obviously that is a lot more work...

The over voltage was cause by the voltage regulator going bad in the old alternator. Causing it to send 17-18V out. but lets keep ignoring that haha
