contamination -Note: This W5A580 transmission TSB is intended to supersede TSB 21-011-05 which included the 2005 Jeep Grand Cherokee Problem – Owners may experience a shudder vibration and/or a high-frequency buzzing sound. This W5A580/NAG1 transmission problem may be most noticeable during light acceleration where partial application of the torque converter clutch happens in 3rd, 4th, or 5th gears. The reason this happens is because water has gotten past the transmission oil fill tube/dipstick seal. Contaminated transmission fluid can cause the TCC to stick and/or slip. Solution – If the contaminated transmission fluid has not caused a lot of damage, the transmission and torque converter may be able to be flushed to cure the problem. However, if the contamination is severe, the torque converter will need to be replaced, and the transmission inspected for signs of other damage. The transmission fill tube seal will also need to be upgraded.

Response Can I drive with a transmission problem?If your Jeep Grand Cherokee can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else. How often does a Jeep Grand Cherokee transmission need to be replaced?The overall lifespan of a Jeep Grand Cherokee transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Jeep Grand Cherokee transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained. How are Jeep Grand Cherokee transmission issues diagnosed?It is fairly easy to guesstimate what the root cause of your Jeep Grand Cherokee transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem. How is a Jeep Grand Cherokee transmission replaced?In order to replace your Jeep Grand Cherokee transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted.

How to Solve Jeep Grand Cherokee Transmission ProblemsSolution A: Buy a Used Jeep Grand Cherokee Transmission The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay. Solution B: Buy a Rebuilt Jeep Grand Cherokee Transmission Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area. Solution C: Buy a Remanufactured Jeep Grand Cherokee Transmission Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission. Need a replacement transmission?
