1994 - 2004: 4R70W 4-speed automatic (4.6L SOHC/GT/Cobra) or T-45/T-3550 5-speed manual 2005 - 2010: 5R55S 5-speed automatic or TR-3650 5-speed manual 2011 - 2017: 6R80 6-speed SelectShift or MT82 6-speed manual 2018+: 10R80 10-speed automatic or MT82 6-speed manual
4R70W servo bore wear: a servo bore repair sleeve can be installed without a full rebuild in some cases ($400 - 700), but high-mileage units benefit from a full rebuild ($1,500 - 2,000). 6R80 solenoid failure: solenoid pack replacement ($450 - 650) first. 10R80 TCC: fluid service first, torque converter replacement if shudder persists.
4R70W: Mercon V 6R80: Mercon LV 10R80: Mercon ULV - critical to use correct spec
Servo bore repair: 1 - 2 days. Solenoid: 1 - 2 days. Full 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.
On a 1994 - 2004 Mustang with 4R70W, yes - servo bore wear is the classic cause. A bore repair sleeve is possible on mildly worn units; full rebuild if bore damage is severe.
No - it's the 10R80 TCC shudder, a known issue on 2018+ Mustang GT. Start with a Mercon ULV fluid exchange. If shudder persists, torque converter replacement resolves it.
Yes - 2nd gear synchro wear is the most common MT82 complaint. Synchro replacement runs $800 - 1,400 depending on damage.
Yes. We use upgraded friction clutch packs and heavy-duty solenoid bodies in builds for modified engines.
It handles normal street driving fine. For sustained track use, a transmission cooler upgrade is highly recommended - the factory cooler is marginal for extended high-RPM operation.
Appointments scheduled based on availability. Honest estimates, no surprises. We've been doing this Serving Chicago drivers.
