Common Indications that Your Vehicle May Need Transmission Fluid Leak Repair

Jake’s Auto Repair • 8 September 2025

Your car’s transmission is one of its most critical systems, and it relies heavily on transmission fluid to keep everything operating smoothly. This fluid lubricates moving parts, cools the system, and enables proper gear shifting. When a leak develops, the fluid level drops, which can quickly lead to costly damage if ignored. At Jake’s Auto Repair, we provide expert transmission fluid leak repair in the greater Phoenix area. Here are four signs that your car may need transmission fluid leak repair.


Reddish Puddles Under Your Vehicle

One of the most obvious indications of a transmission fluid leak is spotting red to brownish liquid under your parked car. If you notice fresh puddles or consistent drips in your driveway or garage, it’s a sign that your transmission system may be losing fluid.


Difficulty Shifting Gears

Transmission fluid plays a vital role in ensuring smooth gear changes. When the fluid level drops due to a leak, you may start experiencing hesitation, slipping, or rough gear shifts. If your car struggles to change gears or feels like it momentarily loses power when shifting, this can be a sign that the fluid is too low to maintain proper hydraulic pressure.


Unusual Noises While Driving

A healthy transmission should operate quietly. However, when fluid levels drop from a leak, metal components can grind together, creating whining, clunking, or humming sounds. These noises usually worsen over time as the leak continues and lubrication diminishes. Ignoring these sounds can result in severe internal damage to the transmission.


Overheating Transmission

Transmission fluid also helps regulate temperature. A fluid leak can cause the transmission to overheat, leading to burning smells. Overheating severely compromises the system and may result in major problems if not addressed promptly. If you notice a burning odor while driving, it’s time to have your vehicle inspected right away.
