What should I do?

Ok guys n gals question here. Things fell through on the 88 so I still have it. I wanted to know which rear-end you guys think would be better to keep? The one from the 82 or the one from the 88, I'm planning on yanking out the auto-trans with over-drive out of the 88 and put it in the 82 since it has the 3 speed auto in it. Theres nothing wrong with the 3 speed auto or anything it has a shift kit in it and all that a works great but I need that forth gear since its my daily driver. Is there anything that I might be over looking also just incase, like should I keep the drive shaft, flywheel and converter out of the 88 aswell? Also I will be parting out the 88 so if someone needs anything just give me a buzz cuz besides the tranny and maybe the rear-end the rest is up for the taking, the car actually runs but the valve seals are bad so it smokes and the 82 is enough of a money pit for me right now...LOL

Is the 88 a 9 bolt rearend?? Either way you will need to use the driveshaft from it. The 3 spd is a different length and that driveshaft wont work with the 4 spd. Im not sure if the crossmember is different but you should have a look just to be sure.

my th350 is the same length as my 700r4

Well I know that all 84-2002 driveshafts are interchangable and the reason 82 and 83 may not fit is because of the different transmissions they had.

is it a v8 or a v6? I could use some parts.....

What do you need?? Ive got a garage full of crap and were moving so its getting sold or heading to the garbage.

PM me some contact info, a buddy of mine could use some body parts if their condition is good.

any interior pieces??? and what color, thanks

if the 3spd has the 9 inch tailshaft, the driveshafts are interchangable. the 700R4 is only 1/2 inch shorter than a th350. and both have a 30 spline output shaft i think.

and yes the crossmember location is different on the 2 trannys. to replace a th350 with a 700R4, you will have to move the crossmember towards the front of the car about 2 inches

I believe its an 88 rs, it has the TBI 305 in it. Im not sure about the rear-end in it except that its whatever the stock one was in 88. The car runs but does smoke when it first started so I figure the valves are bad. Besides the tranny, driveshaft, and maybe the converter and rear-end everything is up for grabs. It has a grey interior thats in fair to decent shape.

So basically I will need to move the crossmember forward and maybe use the driveshaft out of the 88? Other than that it shouldnt be no big deal right just a normal tranny job. Both cars the 82 and 88 are stock rear-ends for their years, the only thing is the 82 has had the shift kit put in it.

well actualy there could be a number of differnet legths for the 700 depending on the tail shaft. they have like 3 different tail shafts i think. the corvette one should be avoided beause it does not have a normal cross member mount. usualy there is like 2 and 1/4 inches between a 700 and 350. thats with the most commen tail shaft.

ridge: a 2004r is the same legnth as a 350 thought so you might want to make sure it really is the 700 and not a 200.

the output shaft actauly has 27 splines on all but a 400 and 4l80E. those have a 32 splines. and you will need to move the cross member back acordily depending on the tail shaft, but like earlyer with the most commen one it will be back 1 and 1/4 inches, and have to shorten the shaft 2.75 inches.

oh yeah i didnt think about that. use the drivshaft that was with the 700 and you should be fine there, but you will need to move the crossmember, backwards, unless the 3 speed is a 400 then you would need to move it forward.

Whats the easiest way to tell what tranny is in the 88? Is there a number on the pan or something I could go look at to find out?

I believe the tranny thats in the 82 is a 350 3 speed and I have no clue whats in the 88. I just know its a stock tranny for the 305 and it had over-drive so thats why I want it.

well im sure someone on here would know wether they came with 350's or 400's. i would guess a 350 but i dont know. otherwise you could just look at the pan. the 400 will look something like the state of texas and the 350 will be squarish with one corner cut off.

well other than moving the crossmember I shouldnt have any probs though right? I have all the stuff thats with the other tranny, driveshaft, converter, flywheel, if needed that should be about it i think isnt it?

I just went outside and looked real quick and counted 10 bolts on the rear-end, I couldnt really see what the pan on the tranny looked like because its raining ofcourse so ill have to do that when I have the time to get the jack out unless theres a code somewhere I can go look at real fast.

yeah but you shouldnt need the flex plate(fly whleel), but i cant remember. i cant remember if the 350 and 700 have the same bolt patern for the torque converter or not but if it wont lign up then yes you will need it but you will have to make sure they have the same number of teeth but i think it should.

yes as long as you use the trany drivshaft and converter from the 88 you should be good to go aside from moving the crossmember, except for the TV cable. do you know about setting up the TV cabel and stuff. it must be dont corectly and you cant run the car without it or it will kill the tranny in a week or two. and your 88 was TPI right, whats the 82? is it carbed or what?

the only 4 spd tranny available in 88 was the 700 so if everythings stock then its a 700r4

the flexplate bolt patterns are the same for a th350 and 700R4. i'm not sure about a th400, but i doubt you have that tranny anway. your 88's flexplate wont bolt on to the 82's crank tho. the center hub that the flexplate slides over is a smaller diameter than the 82's, i know this from experience.

you will probly also need the shifter out of your 88

hmm thats weird.... im positive is was a 700r... and the driveshaft seems to working with my th350... and your car should have the th350.... the 400s were mainly put in trucks since they have a lower 1st gear ratio to get them moving

and yes 4 on the floor is right the flexplate are the same for the 350 and the 700

tv cable, does the 82 have one of those? The 82 had the throtle body f/i system but that was scrapped and it is now a carbed 350 (the 350 is a 68-79 I believe or whatever those years were). The 88 is a stock 305 that has the throtle body f/i in it.

Ok I was able to go look under the 88, the pan on the 88 was a big square and it looked to have a notch (goes in about an inch towards the front of the pan) in the rear of the pan that does not go all the way across and its mostly on the passenger side. The 82's tranny pan is square but has a corner notched out of it. I hope that might help figure out what it is....LOL

Ok....LOL. I just went and looked at the tranny pans on ebay to match them up. The 88 has the 700r4 in it and my 82 has the 350 tranny in it. So now what exactlly will I need to switch them out. As I said I have all the stuff from the 88. This tv cable thing is whats got me kinda worried, so if someone would help me out there id appreciate it. Oh yeah one last thing here, most of the computer stuff has been removed from the car.
