4l80e tcc slip. 0 sec Sys Volts > 8.

4l80e tcc slip The TCC regulating valve sends pressure to the TCC Shifting valve in the transmission pump. 0 RPM Engine running > 400 RPM > 7. The PWM strategy of the TCC will cause slippage at various times. Tcc slip remains at 150 rpm even after line pressure is Aug 23, 2014 · The reasons why are complicated. I just changed it, maybe I got it int here wrong, maybe it was bad out of the box. Apr 19, 2015 · the slip RPM: TCC slip should be below 50 rpm, near zero as the vehicle drives along. Could be the TCC Valve behind it, Sonnax has an upgrade for it, here, Sonnax 34994-01K. Generally the 4L80E TCC system is reliable and predictable with most slip concerns due to torque converter issues (usually OE). On the highway , the TCC should fully engage , slippage is near zero 100% of the work I have done for several years is high performance - race stuff, High HP Jul 22, 2019 · - Watch your TCC duty cycle when it acts up and compare to scenario you mention where it seems to lock up good. 0 sec Sys Volts > 8. Gregg Nader Sonnax Tech TCC System Stuck OFF P0741 This DTC detects excessive torque converter slip when the TCC is commanded ON in 2nd and/or 3rd Gear Only. Why does the TCC valve go bad? PWM. It's 30 bucks, and worth a shot. - If all else checks out good, I suggest replacing torque converter. Jan 14, 2020 · tcc duty cycle 99% Tcc slip - 150 rpm 4th gear commanded If I give it enough throttle to downshift to 3rd Tcc slip goes to 0 and stays at 0 rpm until it shifts to 4th again. (High TCC Slip in 4th gear is detected by P1870 Transmission Component Slipping) TCC Slip => 125. Then tcc slip goes back to 150 rpm Eventually throws p1870 code and trans goes to limp mode and Max line pressure. The 1-2 and the 2-3 shifting solenoids send pressure to the TCC solenoid, the TCC solenoid opens and closes the TCC Regulating valve. 0 for > 0. 5 sec No ISS DTC's No PSA DTC. 0 & < 18. Could be a bad TCC Solenoid. what can be adjusted to lower the slip under full throttle. Aug 23, 2013 · the trans is a 4L80e with a ck performance D3 valve body, a triple billet triple lock up 4300 stall converter , and I am getting 1200-1500 tcc slip in 3rd gear at 5000+ rpm.
