I think it is you need to replace the drive shaft, torque arm, tranny mount and get a painless wiring harness, to lock up the Torque converter. but what else would I run into, that I haven't covered

Torque arm will work just fine. Cut it to fit, it won't hurt it at all. The crossmember is going to be the biggest challenge. You probably don't have the holes in the subframe to mount a 700r4 crossmember and the th200c crossmember is too far forward. I modified (cut and welded) the crossmember to work. Others have welded nuts into the subframe. It's worth the time and effort

When I put a 350 trans in my 83 Z28 which had the 700r4 trans, I notice that both sets of factory holes were under my car! I think that u would just need the cross member.

Yeah, but the cars that came OEM with a 200C do not have both sets of holes, therefore the 700R4 OEM crossmember is not a direct bolt in.

We can build a 700R4 crossmember for an 82-83 200C car if anyone needs one. It bolts right in using the OEM mounting holes and puts the transmission mount hole where it needs to be for the 700R4.

How much would it cost I am definatly interested in that, BTW what about the Drive shaft shouldn't that be shorter because of a longer tranny, so I'd have to get a drive shaft too

Also will I need to replace the Flex plate for the differant Torque converter?? or will the origonal holes be the same??

I also need to know if I need a new Drive shaft.

82camaro

Flex plate will be fine. 700r4/t5 driveshaft is what you need. Most junkyards have a pile of them. I got mine for 30 bucks with good u-joints.

I just put a 200-r4 into my 82 200c camaro, did a really shaky rear crossmember slide back using the two existing big holes in the body into a shortened up with a grinder old cross member, and bent torque arm mount and mounted rubber from it 'backwards' and bolted to crossmember, drove it back to seattle from lake tahoe yesterday. nice, have 2.73 rear end, but I like 1700 at 72 mph, works for me, 22mpg average. Cost $60 for tranny, $20 for fluid and filter, $15 to replace broken rear mount.

Did you have to change the Drive shaft??

How hard is it to find a 200 4R??

Blue Berlinetta

So would it be easier to replace it with a 200R4??

My local pull-a-part had at least 5 200-R4's in their yard. I pulled the pan on 2, a 88 Pontiac SW and a 89 Buick SW, another one I looked at was a Chevy 89 SW. Guess they were in a lot of wagons. The link below tells you all you want to know about all the GM transmissions.

This is a real simple bolt-in. I had trouble getting one of the bell housing bolts out, needed a 9/16th u-joint socket to do it right. Drive shaft is the same, tvi cable is the same, dip stick and tube identical, shift linkage same, detents are on transmission, not at console. The rear crossmenber has to be mounted further back, and I attached a portion of the old one with only two bolts using existing holes in the body. My biggest problem was getting the car high enough. I found a clean looking pan in the Pontiac, took a chance because I drug the tranny fron Seattle to Lake Tahoe to install it blind. used the Pontiac torque converter, chevy drive plate. Pontiac drive plate was not only bigger, but had balance weights, apparently no harmonic balancer on front of Pontiac, I guess. When I firat fired it up, it shook badly, thought I had to use my TC with crap in it, turns out I pinched wiring at top of bell housing, so it was not on fully there, and the rear tranny mount was broken off. Once I bolted everything down correctly, ran like a top. I had no top gear or reverse with the 200c, so it was real nice just to back up!

If you read the link, I think you will fine the 200-R4 is perfect for a 305 or smaller, rated at 330 ft-lbs of torque, maybe not so good for big motor, but for less than $100, who cares?

If you need any more info, I can supply it.

Oh, one more thing, the C in 200c means you had a lock-up converter in your car. Niftily, the wiring harness your car is identical, the plug is the same, all you do is uplug from your 200c and plug into the 200-r4. the third wire from the 200-r4 is for back-up light, and your car does that at the shift linkage, neat, huh?

Another thing, I am not a mechanic, and worked alone in an unheated garage with low clearance, took me 2 1/2 hours to get one bolt out, tranny kept falling off jack while I was trying to muscle it onto jack, that took 3 hours to secure, but I started Saturday at 11am and was done except for fixing the bell housing bolt-up and rear mount by 5pm sunday, had to wait to buy the mount. (mount is same on pontiac, should have taken it)

200-r4 did not have a speedo drive gear or holder in it, and it is not the same on 200c, drove 750 miles with my gps reciever for speedo, not a good idea, car likes to cruise at 85 now! I blew out cooler lines and cooler by flushing with gasoline, there are no 'nooks and crannys' in the system, don't believe the bs about flushing. Get a tranny without any crap in the bottom of the pan, use that converter, and you should be ok like me. Speedo cable seemed a tad short, but I yanked on it and made it fit.

Blue Berlinetta

Cool I just found a rebuilt used 200 R4 for 175.00. all I need is a mount and I'm set.

tpsierra

great, I put in a speedo drive yesterday, next time I get under it I'll take a picture of the crossmember I did, the real trick is holding onto the torque arm that goes to the rear end, I can talk you through it after you see how yours hooks up. old tranny has two cast holes in tailshaft to hold onto the mounts, new one does not.
