How to Confirm Fitment Before You Buy

To make sure it suits your vehicle, work through this short checklist:

• Identify the transmission code on the pan or tag, or ask us to match it from your VIN.
• Confirm the drivetrain (2WD, 4WD, AWD, or front-wheel drive) and the engine size.
• Check the gear count and whether your vehicle needs a specific torque converter or bellhousing pattern.
• Plan for related items you may want to replace at the same time, such as the filter, cooler lines, and fluid.
• Ask our team to confirm availability, condition, and included parts before you order.

You can decode your VIN with the NHTSA VIN decoder and check for open safety recalls on the NHTSA recalls page before you start a major repair.

Signs You May Need a Replacement Transmission

Consider a replacement transmission if you notice any of the following:

• Slipping gears, delayed engagement, or a flare between shifts
• Harsh or erratic shifting, including getting stuck in one gear
• A burning smell, or dark, gritty transmission fluid
• Fluid leaks under the vehicle, or a low fluid level that keeps recurring
• Warning lights or limp mode triggered by transmission faults

These symptoms can point to worn clutches, valve body faults, or torque converter problems, but sensors and fluid issues can cause them as well, so have a qualified technician diagnose the vehicle first.
