: shift range inhibited or somethin. DURAMAX_XJ400 02-21-2008, 10:40 AM was goin on the highway raceing my buddy in his cummings. @ about 90 in 5th gear with the tq converter locked,, truck just kind of died and then would not shift into od.. so i was doin like 60 almost @ redline, stoped turned off the truck and waited a minute and started it again and it shifted fine, threw the check engine light on but what was this, is that ""limping the trans"" ? whitetrash21 02-22-2008, 12:33 AM yup... pull your codes. should have p0700 and maybe another p07xx code. runnin aftermarket tuners will do that. limped mine @ 75 mph the other day.... 135 hp tune. its the heavy foot when the truck is in 4th or 5th that tends to cause the problems.... skiandplay101 02-22-2008, 12:51 PM yup... pull your codes. should have p0700 and maybe another p07xx code. runnin aftermarket tuners will do that. limped mine @ 75 mph the other day.... 135 hp tune. its the heavy foot when the truck is in 4th or 5th that tends to cause the problems.... Done that before. I get an error message on the PDA "tranny slip detected" billygoat7c 02-22-2008, 06:14 PM sounds like a limp, power adder+big tires and it is probably going to happen. X2 on pulling the codes though. stumpjumper 02-22-2008, 08:17 PM there is no "G" in cummins sorry that just urks me gmtech4 02-22-2008, 08:35 PM when a code is tripped ,most have a default programing while the code is current ,some are noticeable ,some are not,it is designed to get your attention,and save itself,example,shift solinoid code trips and PCM/tcm take all power from solinoids resulting in 2nd gear for an older 4L80E,why Allison disables reverse for a TCC code is beyond me,but it does get peoples attention ,new to the forum,hope I wasn't blabbering to much,lol DURAMAX_XJ400 02-22-2008, 09:08 PM there is no "G" in cummins sorry that just urks me haha ture that, my bad. i knew it but i dont follow the 6's lol. | ||
