Compatible with radiator on my 2000 Buick Lesabre 3.8
The Jiffy Clips holding transmission lines connected sometimes cannot be removed, even using the correct tool. I got three of the four clips on my lines off, but for the last I had to cut the pipe with a Dremel cutoff wheel and then remove this fitting from the radiator using a socket wrench. The factory fitting is extremely tight in the radiator and take a lot of force to unthread and remove from the radiator. However, with sufficient torque the fitting will come out without damaging the radiator. A LOT of torque to remove. These Dorman replacement fitting come with thread sealant already installed, and the thread right in easily. The standard GM transmission line metal pipes fit right in and seal properly. Note: It may not be obvious, but the Jiffy Clips are designed to not have to be removed. The removal tool fits around the pipe and spreads the clips without removing them. The pipe pulls out through the removal tool. To connect the pipe to the fitting, just push it in with the Jiffy Clip already in place. It will go in and lock.

Used on tru cool transmission cooler
I bought two of these to install a cheap eBay tru cool 40k transmission cooler to my 04 Yukon Denali. Worked great and screwed right into the cooler. Stock 4l65e lines mated to it.

Good OE replacement for gm trans cooler lines
Best replacement other than OE. Fit perfect in the radiator.

Leaky O-Rings
Bad O-ring. I bought 2 of these for the transmission oil cooler on my 2001 Chevy Suburban. The fitting is the correct thread, and the thread sealant is nice. I lubed the o-rings with silicone grease, but the o-rings still leaked on both fittings. Like other's have said, not worth saving $2 over OEM. Plan on replacing the o-rings before installing if you want to save some hassle.

Product review; Dorman 800-605 Transmission Line Connector
I mistakenly ordered the wrong diameter of the thread size. Nothing wrong with the product itself, machined from quality aluminum.

Some Dorman stuff is good, this not so much.
Doesn't work as well as the OEM version.
