What Tranny
What auto tranny is in my 1989 4wd 1 ton SRW w/454? It seems to be leaking at the output seal. I was unable to locate a data plate on it. I kinda of assumed it was a TH400 but than I was told today that being a 1989 it may not be.
Thanks Paul |

Or a 4L80E... the bigger, beefier brother to the 4L60E in my DD...
I didn't realize that the "80" was that old...

Ok, so now I'm curious... I know that the 4L60E is just an "E" version of the 700R4... Anyone know if there was a predecessor to the 4L80E???
