Does it have an electrical connector on the driver side near the shift shaft? If so, it's a TH350C w/lock up TCC.

Now as i start all over what will i need to do to make that swap possible? Im kinda upset i didnt pay too much attention but i kno i have a way stronger trans that will hold some hp and maybe roll some heavy wheels if i decide to put my 18s on

here, instead of retyping, i copied and pasted what mentioned up on page 1.
if its a th350, you will have to run a vacuum line from that nipple, to a full vacuum source on the engine. and you will have to buy a kick down cable for the 350 as the cable for the 200c and the 200-4r are not the same as a th350.
oh and i forgot to mention 1 good thing, you dont have to do a thing to the driveshaft as from end to end, they are the same length.

it doesnt have a plug at all so i guess its a non lockup not sure what difference that will make or what ill notice. And i do have a cable with it! Will my 200r4 speedo work in there they look similar? Will the convertor bolt up to my flywheel? And would that be a better choice over the 200c or should i sell and start over?

the 350 is quite a bit stronger than the 200. if mileage isnt all that important to you with this vehicle, id say just put it in and not worry about lockup.
the speedo cable fits on either trans, and the converter will bolt up to your flexplate, just have to buy converter nuts and bolts. 3/8x24x3/4 on the bolts, and 3/8x24 on the nuts.

I agree to use the TH350 as long as it's good, no need to start over w/another weak-kneed TH200.

Not having lock up really isn't a biggie, IMO. And it makes the installation just that much easier, because if it was a TH350C, you'd want to wire up and use the TCC. Running w/o the TCC on the highway will cost you a little mileage over a TH350 w/o lockup due to the looser TH350C torque converter stall when not locked up. The difference is about 200-250 RPM depending on the specific app.
