So i drove another 20k miles. I am changing the tranny fluid and oil tomorrow. I just hit approx 102k.


Is it necessary for the flush? Or can I just change the filter and fluid. I was recommended before to leave some of the old fluid in there, but I was never told to do a flush before.

Track down some GM synchromesh, it's amazing for transmissions. Butter smooth

If i change my tranny fluid at 50k miles instead of 100k what are the risks

Depending on the year/make of the car, some manuals don't even have it listed in the maintenance schedule. Mine does not, either, but I want to check the fluid in the pan.

It won't hurt it at all though, as long as you don't use one of those flushing machines. Most car companies issued a warning with those flushing machines that the franchises and some town mechanics use.

75k boys and girls, flush, fluid, filter learn it and sick to it. Unless in a non standard application (non dd)

prepare to lose a gear

That is for manual transmissions.
