6 Speed Transmission Adapts 6l80 6l90 Shifting Issues Youtube We have received many calls as of late for abnormal shifting on 6 speed transmissions. in this video, we cover the basic procedure for the reset of the trans. 6l80 6l90: issues that could drive you crazy. october 13, 2023. 8,287 views. 9 min read. by now, most major shops have had enough exposure to 6l80 transmissions to realize that they will be around for quite some time, providing plenty of work. patterned failures for this unit have been covered in previous editions of gears magazine, but there.
Gm 6l80e 6l90e Transmission Problems And Performance Upgrades 19179 posts · joined 2012. #3 · aug 16, 2016. the government forced cafe is your problem. i have the same 6 speed and usually "around town" legal speed is 30 mph. my truck wants to be in 6th gear and v4 mode most of the time. 5th gear is overdrive, 6 th gear is the 2nd overdrive. 30 mph in overdrive!!!!!!! you wouldn't drive a manual that way. Clutch failure. first gear slipping. reverse gear engagement failure. cracked clutch drum. stator support issues. cracks in the 1 2 3 4 pistons. issues with the 1 2 3 4 pistons are common in 6l80 transmissions. the piston typically gets cracks that result in clutch failure. however, gm updated the piston. If the transmission is failing: it might skip gears. it could be slow to engage into drive. it is likely to start slipping. a smaller repair bill. if the transmission has likely failed (red alert!): the truck will not move – sometimes called p n n n n n (park neutral neutral….). The 6l90 transmission is a six speed hydraulically operated automatic transmission designed for longitudinal engines and particularly for rear wheel and rear focused four wheel drive vehicles. built in 2007, this tranny consists of six forward gears and one reverse gear.

The 6 spd auto trans control moduel is in the trans itself. the ecu is by itself that control the engine. so for these 2 modules to talk communicate with each other it needs a can circuit network. by removing all other module except these 2 will more than likely not work. the speed signal is put on a can network so the ecu, cluster, bcm, etc. Problem #6 the transmission electro hydraulic control module (tehcm) problem #7 the 4 5 6 (overdrive) clutch pack problem #8 the 1 2 3 4 apply piston conclusion to the 6l80 e transmission. introduction to the 6l80 e transmission: the general motors 6l80 e transmission is one of the most widely used 6 speed transmissions in.
