Expert Chevrolet Tahoe 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.
Same transmission diagnosis as Silverado - Tahoe shares all transmission components. Transfer case chain wear is a separate but common companion repair we frequently do at the same time as transmission work.
6L80: Dexron VI - change every 40,000 miles Transfer case: Auto-Trak II - change every 50,000 miles
Transmission rebuild: 3 - 4 days. Combined transmission + transfer case: 4 - 5 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.
Likely the NP261 or NP263 transfer case chain - not the main transmission. Chain wear causes a distinct clunk when 4WD engages. We service both at the same visit.
Yes - identical transmission, same rebuild process and pricing.
It's a 4L60E sun shell failure - rebuild required ($1,500 - 2,000). Not an emergency repair but do not drive it - you risk secondary damage.
3 - 4 business days.
Yes - we strongly recommend servicing the transfer case chain when pulling the transmission. They're adjacent components and combined service saves labor.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
