Hello, I am trying to get this old truck up to reliable condition as a 3rd vehicle/farm truck. I have replaced a ton of parts on this thing and have come to the conclusion that its a transmission issue. The truck runs great however when you put in reverse or drive, it stalls all the time. When I come to a traffic light, the thing is barely alive (Idol is low). I replaced the IAC, Throttle position sensor and a slew of other things but got to reading that it could be a TORQUE CONVERTER CLUTCH SOLENOID. however I am not sure which one I need or if its that accessible when I drop the pan. Every video I find seems to be for like a 99 or newer 4L60e. Has anyone had any experience with it? I am pretty mechanically inclined but am not sure if this exists on the OBDI system as every youtube video talks about OBDII engine/transmission codes. Last time I dropped the pan (after buying it) it was NASTY black. Changed the filter and fluid and its about time for me to run through it again since it was so bad last time. Anyways..

The trans feels like its engaging at idol to hard. Park and nuetral it idols fine all day.but once in gear it feels like it really has a load on it.

Thanks,

I found that my 1995 5.0L g10 has a 1994 5.0L k1500 transmission, and had a computer chip for a 5.7L, causing many fake errors. Cooked my fuel pump a few times due to the near double difference in fuel line pressure, still combing forums how to resolve the 94 4L60e in a 95 due to PWM TCC Lockup being introduced that year. Anyways, codes might be lies. Check vin codes on motor, trans, body, and verify it's got the right computer and chip, I'd imagine someone slapped a junkyard computer in there like mine had.
