TRANSMISSION ID

[Trond Stordal]

Greetings from Norway. I just bought me a '91 2500 Sub, and i am about to change oil and filter on my transmission. I thougt i had a TH700R4, but this one got 17 bolts in the pan. Is it a 4L80? Thankful for answers.

1991 was the introductory model year for the 4L80-E. The diesels and the 454 got the 4L80-E. smile.gif
