First check is whether the fluid level is correct, as low fluid level can cause shifting problems. Look for obvious signs of fluid leakage around the transmission.
While the fluid can be changed, there are two schools of thought. Replacing fluid adds new fluid that by design has a high level of detergent in it. That can clean out the transmission, and since there isn't anywhere for the residue to go, it can cause problems in the valve body which has lots of small passages and check valves. Transmission failures can be precipated by changing the fluid in a transmission that is otherwise fine, expecially at higher mileage. Others feel that clean fluid is better than dirty fluid, and that all transmissions that fail after a fluid change were about to fail anyway. If the fluid level is correct, and the shifting problem is enough to be noticeable, then you can always decide to change the fluid based on not having anything to lose. I would probably do that myself. If a fluid change doesn't have any effect, take it to a transmission specialist for diagnosis. Your dealer doesn't repair transmissions, so you would need to find an independent that you trust.

Look at the tag on the transmission. Get it from your dealer, that is the safest bet, and it won't matter much because you will only be adding a litre or less. It is probably Dexron, but it pays to be safe.

I decided to do it by myself. I assume I need to get Infrared thermometer to check the tranny temperature before adding the oil. I'd like to know which one will be OK to use. I found the one for $29 here: Non-Contact Infrared Laser Thermometer. will be this a good choice?
What is the tranny temperature should be on adding the oil? Thank you again! Last edited by vladc77; 02-19-2013 at 02:54 PM. |

The ATF should be changed at intervals of 160.000km or 100.000mls. The revised Maintenance booklet states this.
Back many years ago, there was a software update that slightly alleviated this problem, where 3rd and 4th gear hold gears too long when going up a gradient. Obviously you are out of warranty, but if you are willing to pay, you could ask and see if the dealer still has the EGS update and how much they charge for the service. |
