Its a three speed i think the dash indicator indicates 3spd too. Its not turbo charged any more. So i wanted to do some checking to see if there was anything different with the trans. I assume that some one switched the motor and not just took the turbo stuff off but idk.
I guess basic question is is there anything different about t type trans vs. regular car. ie shift points gearing stuff like that

Most '83 "T" types were built with the 200-4R(MW9 on RPO sticker), but the 200C 3 speed was still used(MV9 RPO code), check your sticker on the underside of your decklid, that is what "Your" car/decklid was built with.
Don't be surprised if someone has changed out the transmission during it's lifetime. Check codes, then Identify what trans "IS" in your car, go from there.
Good luck,
Kevin.

Great add TexasT and I thank you,
Still many new users can get confused with TH200/200C/TH250C/350/350C
The 200 came out in the later seventies and was what caused a lot of trouble for GM, as well as their engine use in certain carlines, back then people said it was a "350" without a modulator..little did they know.
The TH200C came around in late '79 and was used throughout the '80's rwd carlines, it is identifyiable by it's lack of a vacumn modulator on passenger side rear and a square electrical plug on drivers side case area(above pan level)
Now we enter the TH250C, (always gonna be an outcast somewhere)
from the outside, you will swear you have a TH350C(modulator on right rear/electrical plug on left),...But the tell-tale is looking at the cooler line connection area of the case...if you see an external adjuster nut and stud(usually caked/covered over by oil collection) just aft of line fittings, this is yer gal. actually not a bad trans, just gets screwed over by people that don't know it.
The TH350 has been a main player to many GM carlines and even more car guy's, which is also it's weakest link....just how many other people have screwed with it before you did? Had modulator on right rear side pointing away from engine, no electrical plugs/connections on left side but may have a pronged switch on right side of case near fill tube(looked like engine oil pressure sending unit, was used to trigger EGR action from the early '70's).
That brings us to the TH350C, which shares very little with a "real 350" for consideration, different converter/pump/input shaft/case/valve body, have messed with more guy's than you can count trying to get parts, looks just like any other 350 except it has a square electrical conector on drivers side.
If you still have trouble determining "which" trans you have, look at the pan pictures above in TexasT's post, the others are obvious.
Good luck,
Kevin.

I sure ain't no guru but I have that pic that seems to help dispelled trans I D issues.
I got my book on the 700r4 / 4L60e in the mail so I am going to attempt a rebuild for my Suburban. I'm sure I will have plenty of questions. But enough of my hi jack.

Well thats the shyts crawled under it for the first time since i got it. I have owned it for a year and havent done anything with it. But i looked at the dash and it says its a 4 speed. Good i thought i have a 442 that needs an od. But when i drove it i swear it was a 3 spd. Looked under it and its a 200 with a boger welded piece to extend the crossmember forward.
