Hi thank you for your question hope this helps.The check engine light is telling you there is a problem with one or the engine / transmission sensors.You need to have the computer scanned to pull the trouble code. With this code I can tell you the problemYou have the NAG1 transmission There is just two small problems. 1. The NAG1 transmission does not come with a dipstick. 2. To check the fluid level you need to compare the transmission fluid temperature to a chart to find the range on the special dipstick. The dealer is the only one with this dipstick. NOTE: Too much fluid will damage the transmission AND too little fluid will damage the transmission.
I have had my motor oil changed at least three times on regularly scheduled changes, and usually the oil change mechanic is suppose to check all fluids, from washer fluid, to oil both, power steering, and filters. If I need the fluid for my transmission how would I know if the fluid is low if I can't check it. I will have the dealer check the engine trans sensors as directed. But in most cars there is usually a lot of time before tans oil is changed, right? or no
