Tranny pipe stuck to radiator. A bad thing?

Question

My 1998 GMC Jimmy just had some work accomplished and the mechanic noticed that he could not flush the transmission due to the pipe being frozen to the radiator. How can I fix this problem without breaking something and having it cost a fortune?

Thank you!

Answer 1

It's possible to cut the pipes, then with a flaring kit put new connectors and couplers in line. This isn't something I would recommend for a novice. It would certainly be cheaper to have a qualified mechainc perform this work than have him pull the radiator, torch off the pipes and install new ones. Especially if you just want to keep the car running.

It sounds like you might need to find a new mechanic, stay away from the monkeys at jiffy lube. Find a guy who does complete engine rebuilds and has a clean shop.

Answer 2

Just remove the transmission pan and change the filter every 30,000 miles. Total flushings are best however. The metal line has a E clip that holds it in the radatior and may require a special tool to get it to release.

Answer 3

Put some kind of lubricant on the spot where it's stuck.It might just be some corrosion sticking it, and let it work for a few days.(cover the spot with grease or add WD-40 every day) Some of these other guys, looks like they are for making money for the shops they work for. Don't cut your pipes, lube the spot and try again later. Good Luck!

Answer 4

I guess you mean that the tranny line not being able to unscrew from the radiator so the tech can hook his equipment into the line?

If this is the case, you need some kind of "nut buster" spray to loosen it up. Usually that doesn't need to be unscrewed to flush the tranny (It doesn't in my Jeep, anyway).

GOOD luck.

Answer 5

Cut the pipe at a long straight stretch, flush the trans, then splice it with a compression fitting. Run it by your tech and see if he wants to try it.
