Hey
I am in similar boat or SS. I deleted the computer and have a 383 stroker. Does the 200 R4 has been upgraded to handle the 425hp but curious do you need the computer for shifting issues or is it a non issue. ??? Any help appreciated

The computer only controls lock-up, as I stated above, you can get a kit to make it work, good luck!!

If you have problem shifting, check your TV cable. Maladjusted cable with that much HP will kill the trans in no time. Stock engine kills trans with maladjusted cable in short time. Imagine with that much power.

Also, what kind of upgrade did you get? From where? There's only few places that understand our beloved 200-4R.


1986 Silver MCSS - Poly bushing and Hotchkis spring w/Bilstein, Posi w/3.73, MSD 6-AL, E-Brock 600cfm, Aluminum 2-row radiator.
1986 Black MCSS - R.I.P............Finally.

Thanks. Lock up kit is definitely in the next step, the upgrade itself was done by a local transmission shop in NH that works on a pretty wide variety of cars to include hot rods. Changed out the torque converter and upgraded the internals to handle the hp. Seems good, just seems have to really get on it high rpm's in order for it to shift to second. May be by design, i will hook up witht the tranny shop and see if maybe the cable needs adjusting. thanks.

To me this is a great article on diagnosing and setting the TV cable. Art Carr is well known in the 200-4r world.
