Key Product Information
Additional Information
| FITMENT | Intended for 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 5.3L L84 V8 and the 8?speed automatic transmission option (RPO MQE). Listings specify 4WD applications; verify by VIN before ordering. Chevrolet Silverado 1500 (2019): 5.3L L84 V8 GMC Sierra 1500 (2019): 5.3L L84 V8 |
| SYMPTOMS | Common 8?speed (MQE/8Lxx family) complaints include torque converter clutch shudder during light throttle (typically 25–80 mph), harsh or erratic shifts, and delayed engagement. GM TSB 18?NA?355 addresses TCC shudder on 8L45/8L90 with a full fluid exchange to Mobil 1 Synthetic LV ATF HP; later updates/related guidance exist for MQE shift quality. |
| TROUBLESHOOTING | Before condemning the unit, check for latest TCM calibrations and perform the GM fluid exchange procedure if shudder is present (per 18?NA?355). Verify driveline and mount integrity, and inspect for DTCs related to shift performance or converter clutch. Road test under steady light throttle in higher gears to confirm shudder frequency if suspected. |
| INSTALLATION | Programming required after installation. Retain/use the original transmission calibration ID (TUN) as applicable; unit may ship with a PUN tag. Perform TCM programming/updates and a Service Fast Learn/adaptive reset per GM procedures. Always flush/flow the transmission cooler and lines, replace/inspect external seals and the filter where applicable, and fill with the specified Dexron HP fluid. |
| MAINTENANCE | |
| GENERAL NOTES | This is a factory remanufactured assembly listed as “F Remanufactured Transmission.” Core charge typically applies. Confirm drivetrain (4WD vs 2WD), axle ratio, and RPOs. Body styles (Crew/Extended Cab, box length) shown in fitment are informational—fitment is primarily determined by engine, drivetrain, and RPO MQE. |
