Common 8L90 Transmission Problems and How to Fix Them was created by eliyalily
Despite being a very sophisticated device, the
8L90 transmission
has a few recognized problems. Some GM owners have complained of delayed engagement, hard shifting, or torque converter shudder, which are typically brought on by fluid contamination or issues with software calibration. The good news? Updated software, torque converter repair, or fluid flushes can frequently fix these issues. Using the proper Dexron VI or HP fluid and keeping up with maintenance are essential for prolonging the life of your 8L90 gearbox. The 8L90 is still one of the most capable 8-speed automatics on the market, providing great power delivery and smooth, adaptable performance in both stock and tuned applications with the right maintenance and sporadic servicing.
