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

where your shifter linkages are on you transmission a saginaw trans all 3 shifter arms are on the side cover . on a t-10 2 are on the side cover and the reverse lever is on the tail shaft ,also the t-10 is aluminum and the saginaw is cast iron as far as i know aa

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!!

My 82 T/A 305 4-speed (speed shift) kept having to go into the transmission shop about every year. Spider gears kept breaking. (Also, certain people couldn't drive my car with its speed shift without jamming the linkage and getting it stuck in gear. Had to get underneath to un-jam it each time) Finally I took it to a mechanic at another shop and he found the problem. The spider gears weren't meshing right because it was supposed to have a borg warner in it, not the Saginaw that someone obviously put in before I bought the car. I never had another problem.

I love a happy ending.

The 82 cars came w both 4 speeds. There were t10 supply issues and some cars got Saginaws. So it may be stock.

Most of em got the Saggy.

It's REAL EEEEEEEZZZZZZZZY to tell which one you have; the T-10 shifter has reverse all the way to the left and UP, butt the Saggy has it DOWN.

Never heard of "spider gears" in a 4-speed. Of course I've only been building em professionally off and on for 45 yrs or so, mostly Muncies & T-10s (nobody in their right mind would spend money on a Saggy except as an ultimate last resort), so maybe there's something I haven't ever come across.

Everyone knows they don't have spider gears. They have planetary gears.

Manual transmissions don't have planetaries. Those are in automatics.

It was a joke.

apparently not a good one!

Sarcasm doesn't always come across on the Internet, does it.
