I own a 1992 S10 Tahoe that has the 2.8 L with the 5 speed manual. I haven’t been under the truck to check what it is yet, I was just wondering what the possibilities were.
Much appreciated!It looks like the only manual transmission available is the T-5...RPO code MM5. Check your glovebox for a sticker that has the RPO codes on it to confirm. Here's where I got the info.
