I just installed a new Circle D single disc torque converter and I'm trying to adjust when it locks up. With the stock T43 tune, at part throttle, the rpms just hang in 3rd gear so I want to lock it in third but not at WOT (WOT > 50% TPS).
Looking at the tables, it seems that there is a conflict between WOT Control Speeds and the Normal/Pattern A/Pattern B/TUTD Control Speeds at 100% TPS. For example, D2237 3rd WOT Apply Speed, Normal is 21 MPH, but the Normal Control Speed Table its 217 MPH at 100% TPS.
I'm a newbie and just trying to understand.
Why the difference in the 2 Tables?
Is 100% TPS different than WOT?
Is there some other table that adjusts these numbers?
In the Normal/Pattern A/Pattern B Tables, why aren't the 1st, 2nd, and 3rd Apply speeds 318? For the Normal Table they are 318, 132, and 217 respectively.
Also, Circle D recommends 0 slip when locked up. The only reference I could find to slip is D2216 TCC Lock Pressure Ramp. Is this the right Table? If not, then what is?
One more question, Is Normal the "D" mode and Patter A the "S" mode? What is Pattern B? Oops that was 2 questions.
