Is changing the transmission oil in 94 grand jeep Cherokee good maintenance?
hello, if your car/engine/trans have less than 100,000 miles on
it, it's okay to replace the transmission oil (and filter) in your
jeep. if you have higher mileage, it's not a good idea because the
transmission could start slipping. I recommend changing the filter
on an Automatic at 30,000, then every 60,000; and flushing the
fluid at 60,000 then every 60,000 after. I have been told by
transmission rebuilders that if you don't change the fluid and
filter, you can expect trouble regardless of the miliage. Granted
it may bring trouble to surface more quickly. I have only seen this
on one Lincoln personally. It is critical that the proper fluid is
used. Chrysler products such as Jeep require a certain fluid. ATF +
4 in this case. Yes.
