Spent a great day at the Twin Cities Roadsters Swap Meet at the fairgrounds in St. Paul, Minnesota today. I was hoping to run across a T-5 for a good price. Well low and behold a guy there had one. I shifted it through the gears and everything felt good until I tried 5th. Nothing. So, thinking I'd end up rebuilding it anyway, I talked him down and dragged it home. After bolting it up to the dummy block in my chassis, I pulled off the shifter to see if there was something blocking 5th gear. Apparently there is no 5th gear in this transmission. I could clearly see the shift gate below the gear selector and there was no slot for 5th gear. It looks like every other T-5 I've seen and the dude I bought it from said he pulled it out of an S-10, but all those 4 speeds had an integral bellhousing. It's got to be a mid to late '80s transmission as it has a mechanical speedometer drive. What is this transmission?
