Expert Buick Encore GX transmission service in Chicago. Free computer diagnostic, 2-year / 24,000-mile warranty on rebuilds, all years.
We will contact you as soon as a service member is available by call, text, or email.
2020 - present 1.2T FWD: CVT (continuously variable transmission); 137 hp 2020 - present 1.3T FWD: 6-speed automatic (6T45/6T50); 155 hp 2020 - present 1.3T AWD: 9-speed automatic (9T50); 155 hp AWD models: active twin-clutch AWD system
Encore GX diagnosis depends on which powertrain is installed. CVT models: belt and pulley inspection at 80,000+ miles or when slip or surge is present; CVT fluid replacement is the first service step. 6T45 models follow the standard solenoid and wave plate protocol. 9T50 AWD models: software update first for shift complaints, then fluid inspection, then mechanical diagnosis. AWD coupling click on cold starts is often normal engagement behavior - persistent click in warm conditions warrants coupling inspection.
CVT: GM-specified CVT fluid (proprietary), approximately 6 quarts; 6T45: Dexron VI; 9T50: Dexron HP
Software update: same day; fluid service: same day; CVT belt: 2 - 4 days; 6T45 solenoid: 1 - 2 days; 9T50 rebuild: 4 - 7 days
Every vehicle needs diagnosis before anyone can promise a repair path. These are the situations we help organize before you decide what to do next.
Tell us when it happens, whether reverse still works, and if warning lights are on. A scan and fluid check come before guessing at a rebuild.
Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.
A failed solenoid, valve body, converter, or internal clutch problem can lead to very different repair paths. The goal is a clear diagnosis and written estimate.
Yes - GM-specified CVT fluid is required. Standard ATF or generic CVT fluid causes belt slip and premature wear. We always use GM-specified fluid for CVT service.
After software updates, the 9T50 in the Encore GX AWD has been solid. The main maintenance item is Dexron HP fluid changes every 40,000 - 45,000 miles. Early 2020 production benefited most from the TCM calibration update.
With proper fluid maintenance, most CVT belts last 100,000 - 130,000 miles. Neglecting fluid changes or driving with persistent slip accelerates belt wear significantly. We inspect CVT fluid at every oil change interval.
The Encore GX is a larger vehicle and uses a different powertrain lineup - including the 9T50 9-speed automatic on AWD models, which the smaller Encore does not offer. The 1.3T GX also produces more torque than the Encore's 1.4T, requiring the higher-capacity transmission.
Yes - the 1.3T AWD is rated for 1,000 lbs tow capacity. Light trailer use is fine, but we recommend annual transmission fluid inspection if you tow regularly, even with light loads.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
