6l90e Transmission Controller
- The 6L80/6L90E transmission fills a much needed duty gap between the versatility of the 4L series and the Allison variety. All previous GM transmissions had been based on hydraulic controls with more electrical aspects with each upgrade, but this unit was developed as a electro/hydraulic controlled transmission.
- 6L80E / 6L90E TRANSMISSION FILTER: 710019. $15.95: Master Overhaul Kits Complete rebuild kit includes all paper, clutches, steels, seals and rings. The 8L90E kit includes filter and Raybestos’ upgraded friction components manufactured with GPZ high energy fibers for ultimate stress and high durability. Application Part # Price; 8L90E MASTER.
The 6L80E transmission is prone to issues that include: 2-3 harsh or delayed shifts, harsh or delayed shifts from park or reverse, burnt 1-2-3-4, or 3-5 reverse clutch, check engine light (DTC P0751 Code), converter shudder due to flaking of the converter lining, shudder on low/reverse apply, TEHCM and/or CAN software malfunction.
The 6L80 (and similar 6L90) is a six-speed automatic transmission built by General Motors at its Willow Run Transmission plant in Ypsilanti, MI. It was introduced in late 2005, and is very similar in design to the smaller 6L45/6L50, produced at GM Powertrain in Strasbourg, France. It features clutch to clutch shifting, eliminating the one-way clutches used on older transmission designs. In February 2006 GM announced that it would invest $500 million to expand the Toledo Transmission plant in Toledo, Ohio to produce the 6L80 in 2008.
