    hello all, had some trouble with my old 5-Speed manual (lost all the gears except 4th) and decided to swap it out. i got myself a TH-350(turbo 350) and was looking at my wide selection of torque/Stall converters and alot of them depended on what gears i had in my rear end. i have been googling for the past hour and 1/2 and i havent found a thing. can anyone suggest a place to look or any other information that comes to mind? i was kinda wanting to find out without having to tear in there and risk losing parts. (or more likely not being able to put it back together :neutral:) i thought about calling someone from Chevrolet or GM but on their websites they only offer info on their new stock ect.

    thanks for the welcome and that's a good advice. my soon to be father in-law has an '88 model of the truck and has worked ALOT on his. he said that he thinks that they are 3.08 but he isnt positive. hopefully someone can answer my question soon

    Isn't there a transmission code in the glove box? My 98 has the codes on the glove box lid(inside).
    Get that code-maybe 2 letters & a number and check what diff that code says.
    Once you have the code there are plenty of sites you can look it up.
    I think GU4 is 3.08 will show what the codes mean.

    You can look in the glovebox and there is a sticker with a number of letter/number combinations. These are RPO codes. from here you can type in Chevy RPO codes on google and it will come up with different sites that have a huge list that you can then decode.
