The transmission in my M1028 has been acting odd lately when I first got it I dropped the pan and changed the filter, fast forward 4 months and best I can tell the pump starts whining and the shifts get sloppy. After some reading I changed all the rubber vacuum lines and replaced the filter again after which the truck immediately went back to normal with slightly later shifts from the vacuum adjustments the filter was also the same as the original replacement. Got a month out of it this time before the pump whine started and this time lost 3rd gear the same day the pump started whining, ordered a different brand filter, replace refill she drives good as new now again????
The truck is my daily driver and does a fair bit of 50mph running everyday when it is running and when dropping the pan both times there appeared to be small droplets of water in the bottom but no large chunks of anything and the magnet was relatively clean. So I'm just curious if I have been getting bad filters causing starvation, some sort of coolant leak, or the trans itself is just on the way out?
Thanks,
Thomas
