Resist the temptation to tap down into second gear going into the turn. The workaround to the 4L's inherent freewheeling design is to put your floor shifter or column shifter into 3rd gear, then tap up/tap down between second and third gear. Paddle shifters need to speak directly to electric shift solenoids.
4l60e shift kit tuning manual#
I wish this were the case, but the push button connects to the manual valve and frequent up/down shifting through the manual valve will turn your transmissions into hamburger. Steve, it would be great if you could integrate something like this with your paddle shift, thus eliminating the engine braking problem with the 4L60 in OD. We can sometimes fudge the tune to fix a lazy 2-3 upshift. ) The smart folks step up for the right converter, a shift kit at the very least, and some tuning time. We take calls to to deal with that issue all day long. I'm guessing Lydia has had some tuning done.Ī bone stock 4L60E transmission with the wrong converter and the wrong tune will take forever to shift - especially as rpm approaches redline. The OE's actually dumb down shift times to avoid scaring average consumers. That video "feels" like 300 to 400 millisecond shifts. "Lydia", a truly amazing beauty by the way shifts about as quick as anyone can hope for. The 6L's - being clutch to clutch shift darn quick. The biggest amount of delay takes place within the transmission itself. A loose converter definitely takes longer to complete a shift than a tight converter with a locked up converter taking the least amount of time. From there some trans controllers process shift requests more quickly than others.
Paddle response time is defined as the delay between when the paddle is depressed and when the trans controller receives the request. I want mine and we hope to sell these and report back. The PCS system appears to have all the bases covered. Because PRNDL function is safety critical, we shied away from these automated devices in the past. Proper redundant safety measures appear to be in place. The PCS system's action is positive and consistent action. At about 1/3 (or maybe even 1/4) the size of the Mastershift system it is compact. With a 3 pedal car, net power to the driven wheels during the shift = zero.Īs for PCS's pushbutton shifter, we can't wait to try one. Power gets through while the shift is happening. System = Transmission + Converter + Computer + Input Device.Īlso remember the following in contrast to a 3 pedal car: With most automatics, power is still being transferred to the driven wheels DURING the shift process. I can't tell you how many people call to claim that their paddle shifter is shifting slow when the paddle shifter signal time, in itself, is fixed at 125 millisec. Those types always seem to have the highest post counts.And the videos of the wannabe manumatic company who's car bounces off the rev limiter with every shift? Yeah, it's the trans and converter.
Some have dragged transmissions out of the junkyard, sprayed them with rattle cans, then complained when their shiny but worn out transmissions don't shift quickly. That is correct and so refreshing to read.Ī well built, quick-shifting transmission and matching converter are the cornerstones to fast shifting - not the input device.
