Anyone have a 200-4R in a GS? What is the best least expensive way to get this accomplished? Does the stock driveshaft work or does it have to be cut? Is a lock up or non lockup the best? What rear gear ratios are best. What are driving impressions? I have TH-350 right now and am considering going this route if not too complicated. Thanks, Dan
I don't actually have one myself, but I looked into it a while back. I think that the driveshaft does have to be cut a little bit. To handle the torque of a 455 they have to be built very stong, and can cost some major $$$. If it were a stock 350 I would imagine that a stock 200-4R would be OK. Lastly, 1st gear is lower in the 200-4R so you do not need as much gear as you would with a TH350 or TH400. Again, this is just some of what I learned when I looked into it about 8 months ago. But that might give you an idea of what you are looking at. I know there are a dozen or so people on here with 2004R's, just have to wait for them to give a little imput.
i don't see the point unless you plan on a lot of highway driving. the last owner of my car swapped a 200r4, which means instead of a th350 i have a weaker transmission with an OD i never use.o No:
:Smarty: I'ts not necessarily weaker than a TH-350 and with anything more than a 3.08 gear, you can realize less wear-&-tear and improved mileage over the 3-speed auto by cruising in OD.
The good thing about a 200 r4 is that you have the OD gear so when you put steeper gears in you can still cruze around town comfortably....my Olds has a metric 200...its got one hell of a take-off with 2:78's on the first gear, but to cruze with 3:73's in the rear the car tach's at 3,000 rpm.....its a little bit uncomfortable for my taste, but when you hit the gas :eek2: the dam thing take off well like a rocket :laugh: get it rocket....olds....:laugh: :TU: Larry :TU:
I have a 200-4R in my 72 GS and I think it is the perfect trans . I run a 3.31 axle, and the rpm drop at 70 MPH is from 3200 to 2100 ,and the wife will ride in it again. The Flowmasters at 3 grand are a little much for her but the decibel level drops in half with the 200-4R. I also picked up almost 4 MPG ,and the car is a 3990 lb convert that runs 13.0s at 105 in street trim
Depends how built your GS is. If you have a 350 or stock 400 or 455 , no problem with a stock 200-4R. Beyond that, you need one built for higher performance. I love mine, great pickup and better mileage. But, I'm not a racer.
