Identifying my transmission

[84 Shorty]

So the previous owner told me it had a 3 speed transmission in my 84 C10. I got it out on the highway and can definitely tell it’s a 2 speed. Also feels like a shift kit was put in. Is there a stamp on the case or something I can reference to find out exactly what I have without taking it somewhere?

Most are identified by the shape of the pan.

Take some pictures. We like lookin at trucks...

Did it shift twice? If so it’s a 3 spd lol

Looks like I got a TH200 judging by the oil pan. Aren’t the 200s ****?

Could be a 350 too, need to see more of the bolt pattern on the left side of the pic.

Yea I think it’s a 350, I counted the bolts and it’s 13. The 200 has 16 I think from what I’ve read.

The TH200 in the picture has 11 if I counted right. The TH350 has 13, though.

Good to know that it’s a 350

My TH400 feels like a 2 speed too. I seems like it needs 3 or 4 more gears at highway speeds. I would like to put a 4L80E in it but that project is low on the list at this point.

I’m not sure that was meant for anything but humor but I know what you mean. I used to be on another forum and when I asked a question there was one guy who would immediately answer, act like I was stupid and almost never paid attention to the question or had the correct information. I saw he did it to everyone so I didn’t feel singled out but when he did it to a guy asking about a source for wheels for his pro touring truck, the OP got a list of things this moderator(yes moderator) would change about the truck and told him his wheels were fine. I PM’d the guy and told him to come over here. Don’t know if he ever did but I hope so.

So in conclusion, feel free to ask questions and don’t get discouraged if you’re feeling slighted. I’m a bit of a smart ass myself and I’m not sure it always comes across the way it was meant but I would expect to get called out if I offended someone.
