I came across a message mentioning that there were two 4-speed transmissions used in 1982, a truck-like Saginaw and a T-10 (Borg&Warner?)

Is there an easy way to tell which of these transmissions I have on my 82 T/A? My reverse is located top-left and these numbers are on the side of the transmission case:

13-04-065-904
W.G. DIV.
4Q

i would think that "W G div" refers to warner gear....i really dont know any specifics though

I have a '82 T/A 305 4-speed. The original tranny was a T-10 and reverse is left/up. I wasted it and got another at the junkyard. Turned out to be a Saginaw which had reverse left/down. I also remember the other one had W. G. cast on the side. I am pretty sure the T-10 is cast-iron and not aluminum like the t-5's.
How is your clutch linkage holding up? Just wondering.

I took a look down under and there are two shifter levers on the transmission side cover, then a third lever on the transmission case extension. It looks like it's cast iron however. The clutch housing is a different metal, perhaps aluminum? I didn't have a magnet handy at the time so I can't say for sure.

The clutch seems to be holding up pretty well. It's the first stick I've really ever driven, but compared to a few other cars (some 90's cars and a 77 T/A) it feels a bit tight, with a very narrow "critical point". Is that normal for the older non-hydraulic clutches?

One thing I did notice is this car can crank the starter with the clutch up. The connector that should be going to the switch is laying in the fusebox with a jumper across it. My guess is this was the previous owner's poor-boy security system.

The side cover on the t-10 has a "D" shape that faces downward with 9 bolts.

The side cover is definitely a downward facing D plate. It looks like it could be 9 bolts as well (my digital picture is partially blocked so I can't say for sure).

So it looks pretty promising that I have a T-10 based on everything so far..

Thanks everybody for the info!!
