CHEVROLET TRUCK TRANSMISSION PROBLEM

1997 Chevrolet Truck • 128,000 miles

I have a 1997 5.7L 4WD C/K 1500 with just over 128k miles. This past weekend I had the return coolant line pop off as I was heading down a local highway. I pulled the truck over immediately and had the truck towed home. The hose came off becuse the previous owner installed the hoses with a shotty hose clamp. Replaced the hose clamp, started the truck up and began to add trax fluid periodically engaging the trans to get the fluids flowing. After about 10 quarts the dipstick stayed at the full line. I decided to test the truck out and go around the block. Put it in drive, it lurched forward without giving it any gas and shifted into second fine then at about 25 mph or 2200rpms the clutch sounded like it was spinning freely. It didn't want third. I put the truck in reverse and went as fast as I safely could because I heard this has the chance of fixing this sort of thing, but no luck. I tried letting the truck sit idling for 45 minutes in hopes that the fluids just haven't worked their way completely through the transmission. I'm out of ideas. I refused to believe there is anything wrong with the tranny when there wasn't anything wrong before this hose came loose. Any suggestions?

Sounds likes you damaged the transmission from the fluid loss if there was nothing wrong with it before. You loss 10 QTS the transmission was about out of fluid.I had a 1978 camaro blew a transmission cooler line after that replaced the line and fluid. As soon as the transmission fluid would warm up it would drop out of third and would only have 1st and 2nd. It doesn't take long to damage a transmission with being low or out of fluid. Just like a engine low or out of oil doesn't take long to damage it.

If you want you can get a transmission pressure tester kit and we can do some pressure tests the one like mine is about 60 something its a nice one that has two gauges and a lot of fittings. If the pressure is good then we have a internal failure. But if it shifted fine before the fluid loss then I would say it was damaged By the fluid loss.

Obviously not what I was looking forward to hearing but thank you. I will go rent a transmission pressure tester kit from auto zone and try it out.

Your welcome sorry for the bad news but that's what makes the most sense to me if it was fine before the fluid loss.
