The Ascent CVT carries more torque load than the 2.5i version - fluid maintenance is critical. We service with Subaru CVTF-II and check the transmission cooler every visit. For towing applications, we recommend an auxiliary cooler. Software updates from Subaru address shift hunting on 2019 models. Overheating-damaged CVTs require full rebuild or replacement.
Subaru CVTF-II. Critical - do not substitute.
Verify exact spec on the dipstick label or owner's manual before fill. Recommended change interval: every 60,000 miles for normal driving, 30,000 miles under severe service (towing, stop-and-go, hot climates). Pan service typically takes 6 - 8 quarts; a full fluid exchange takes 10 - 14 quarts depending on cooler-line capacity.
Fluid service: same day. Cooler install: 1 day. CVT rebuild: 3 - 4 days.
Fluid service and inspection complete the same day. Solenoid or sensor replacement: 1 day. Torque converter or seal repair: 2 - 3 days. Full rebuild with road test: 4 - 6 days. Time estimates assume parts in stock - call (312) 626-8759 to verify availability for your specific vehicle.
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 - at the rated limit, in moderate conditions. But the CVT runs hot under sustained towing. Watch the temp gauge, add an auxiliary cooler, and service the fluid every 25,000 miles if towing regularly.
Likely a software issue - Subaru issued TSBs for shift hunting on early 2019 Ascents. The dealer can flash the update. If the surging continues after the update, the CVT needs inspection.
Same TR690 unit, but the Ascent's 2.4T puts significantly more torque through it. This makes thermal management more important - the Forester's naturally-aspirated engine is easier on the CVT.
Yes - 5 years/60,000 miles from Subaru. After warranty, we offer competitive rebuild pricing with our own 2-year/24k warranty.
Fluid exchange every 25,000 - 30,000 miles, auxiliary cooler if towing, avoid sustained grades at high load, and don't use aftermarket CVT fluids.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
