Symptoms of Transmission Problems

Transmission Fluid Leaks
Check the transmission fluid level with the dipstick. The fluid should be clear and reddish.
If it’s low, look for leaks around the transmission pan, seals, hoses, and fittings. A puddle of red fluid under your Jeep means there’s a leak.
Regular fluid checks can help catch problems early. If you find a leak, replace worn seals or gaskets to keep your transmission running well.
Slipping Gears
- Check the transmission fluid level. Low or dirty fluid can cause slipping.
- Inspect the clutches. Worn clutches may need replacement for proper grip.
- Look for internal transmission damage. This may need a professional check.
Addressing these issues can help improve your Jeep’s performance.
Delayed or Harsh Shifting
Delayed or harsh shifting often means there are problems with the transmission. This can be caused by low or dirty transmission fluid, which affects hydraulic pressure and leads to slow gear changes.
To keep your transmission working well, regularly check the fluid level and color. Healthy fluid is bright red. If you notice a burnt smell or dark color, it’s time to change it.
Other issues like faulty sensors or worn clutches can also cause shifting problems. Performing maintenance, including fluid changes every 30,000 to 60,000 miles, can help avoid harsh shifting and keep your transmission in good shape.
Overheating Transmission
###[Old or dirty transmission fluid can cause overheating. A faulty transmission cooler may also lead to high temperatures. Towing heavy loads or driving in stop-and-go traffic increases the risk of overheating.]
- Fluid Quality: Old or contaminated fluid can lose effectiveness, which may lead to overheating.
- Cooling System: A malfunctioning transmission cooler can cause higher temperatures.
- Driving Conditions: Heavy towing or stop-and-go traffic can increase the chances of overheating.
Address these issues quickly to keep your transmission healthy.
Check Engine Light and Transmission Codes
Common transmission codes like P0700 and P0720 can help identify problems. The P0700 code indicates an issue in the transmission control system. P0720 signals a problem with the output speed sensor circuit. These codes can reveal shifting problems or unusual transmission behavior.
Using an OBD-II scanner to read the diagnostic trouble codes (DTCs) provides important insights. Fixing these codes early can prevent further damage and expensive repairs.
This helps keep your Jeep Grand Cherokee running well.
