I own a 2002 Mitsubishi Montero Sport. I purchased the car 2 years ago, it appeared to be maintained well as it was like a new car and it has been running like dream car until now. I noticed what I believe to be a slipping transmission at the beginning of summer. It happened infrequently, but still worries me nonetheless.
I get in my car early in the morning, drive down an alleyway and turn on to a side street, then I come to complete stop at a main street. I see no traffic and push on the accelerator to go and nothing happens for about 10-20 seconds, then it seems to catch, and I head on my merry way to work. Occasionally, it will start to go (just enough to coast me into traffic in a dangerous position) and then cut out and then catch again after the 10-20 seconds. If it happens, it is only at that moment in the day and no other.
I thought maybe it could be from sitting for awhile, but the car actually sits longer at work than at home. (I work too much. Local truck driver…) Whether this is of significance or not, it did not occur during the hottest few weeks of the summer, but other than that, it appears the transmission slips about 2-3 times per week. Could the colder morning temperatures affect anything? Could it be some sort of sediment stirred up in the morning that is clogging the filter?
I was thinking of taking it to the shop and getting it drained and the filter replaced. Would that most likely alleviate the problem?
The vehicle currently has 113,270 miles on it and I am not sure if the transmission fluid has ever been changed as I bought it used at a dealership.
I was reading www.trustmymechanic.com, and it said, “The old fluid was gritty due to metal shavings caused by normal internal wear and tear on the transmission clutches and was acting like liquid sandpaper. This “sandpaper” was producing the friction needed for the transmission to pull itself. When we changed the filter and replaced the old fluid with new fluid, the clutches inside the transmission had nothing to grab on to.” Is this something I seriously need to be concerned about? Thank you all for your consideration! o^_^o
