I'm Awesome
To start things off, I have a stock TBI 350 and a completely rebuilt 20K miles ago 4L60E, the truck is a 4WD and I have plenty of trans cooling, both the trans cooler built into the radiator and a separate auxiliary trans cooler are on the truck. I don’t tow, and I don’t beat on the truck, it’s mostly just a daily driver.
Now to the issues, I’ve had a hard 1-2 shift since the trans was rebuilt, and it’s never liked winter too much. Now it’s 3 years since the rebuild and it’s gotten to the point where I’m saving money for what I believe to be an inevitable trans failure. It’s hard to describe what the truck is doing but I’ll try my best.
When the engine and trans are cold, the truck is at a complete stop, in drive, completely still, then you begin to accelerate, the engine spins up a bit, truck has a delay to actually moving, then it somewhat lightly slams into gear and it begins to move like normal. Most other cars I’ve driven, even older automatics, the second you hit the gas, it moves forward, but this one has a delay before it moves.
Things change after about 10 miles in the 95 degree Oklahoma heat, when at a complete stop, in drive, then you hit the gas, the truck does the same thing as before, but now once the trans finally “catches”, it feels like it only partially catches, the transmission heavily resists the movement of the engine. The engine wants to rev, but the trans won’t let it, and the engine gets bogged down until a few seconds later when the trans finally feels like going and it catches all the way and the engine roars up and drives normally.
After you get it off the line, it works great and shifts like it should, this is the only issue with the trans, and I have no idea what it is. Fluid is mostly red, smells a little burnt, but not bad, it doesn’t leak, and the engine runs pretty well.
Any help is massively appreciated, i don’t even know where to start, I have no experience with transmissions.
