This car has a built 200R4 with a 3000 stall Precision Industries multi disc L/U convertor programed for forced L/U @ 110 MPH. Which should be around 5600-5700 in third gear. Put the car in D, not OD and leave it there all through the run (the car should shift around 5800 so let it do it's thing--that's why they are called automatics)--once you clear the finish line, bump it up to OD and apply brakes. If you forget to shift to OD, that's ok--only difference is you will have engine braking in D--I prefer to use my brakes to stop --not the eng. You definately need to get some experience before putting OUR work on the line. Best of luck.
I don't know there LOT..... we seem to have know it alls on here who tend to think an automatic can be shifted faster & more precisely manually vs putting it in D and nailing it. After all, taking off in D slows down acceleration, didn't you know that?
Are you sure you built this tranny correctly? J/K kidding man!! Good advise.
I guess your info answers my lock-up statement from my earlier post too.:smile:
