Common Repair Conversations

What We Help You Sort Out

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.

Slipping or delayed engagement

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.

Leaks, burning smell, or overheating

Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.

Rebuild, replacement, or targeted repair

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.

Jeep Wrangler FAQ

Common Jeep Wrangler Transmission Questions

Almost certainly the 42RLE solenoid pack if you have a 2003 - 2011 JK. Solenoid replacement is $500 - 750 and restores normal operation.

Yes - the 8HP75 is a strong unit. The extra gears improve crawl-speed control. It does need ZF Lifeguard 8 fluid at 40k-mile intervals.

Usually yes - the NSG370 3-4 shift fork wears under hard off-road shifting. A synchro and fork rebuild is $1,000 - 1,600.

Yes - we service Wrangler transfer cases and can do transmission + transfer case simultaneously.

The manual is simpler mechanically but the shift fork and synchro issues are common with trail use. The automatic is more expensive to rebuild but requires less driver skill off-road.
