It's a recently rebuilt, excuse me, remanufactured 4R70W with only a few thousand miles on it. It may have a nonlockup torque converter but I'll have to verify that. I have 2 of these but the other one has no torque converter and was supposedly leaking fluid, probably from the dipstick hole and has no telling how many miles on it. I can ship it via UPS freight if you're interested in either.
Also, it is JBL equipped. I haven't pulled the sub woofer yet but have the 4 2-way speakers and the AM-FM cassette out. It also has the CD changer in the trunk but I don't know if it works, the front door is broken, and the CD tray is missing. The radio does work.
