I pulled a 454 + an automatic tranny from a '89 Chevy 1ton dually 2wd. I'm not sure what the tranny is. Any input on what was available for that year is greatly appreciated. Thanks
Sorry dude, its not a 400. Thats what I thought it was when I pulled it. No beer for you. I think it is a 4L80E. Does anyone know how to I.D. one of these?
If it really is an 89 model, and it really came stock with a 454, then it *will have* a TH400 factory. If someone swapped in some different tranny, it could be who knows what.
As mentioned, google up some pan images and compare them to it.
The google search worked. Its a 4L80E. After breaking the motor down, it is obvious it has been rebuilt once aleady. The 4L80E probably went in with the rebuild. Thanks for all the help.
