Transmission Time..

[Roysbigtoys]

Not hijack this thread....... but my truck also experienced coolant in the trany oil from the stupid cooler. I was noticing a sporadic shudder/vibration under acceleration. While checking my truck out I noticed a milky substance coming from the top of transmission.......un-screwed the fill plug and it came shooting out. The trany was warm, so I drained it and flushed. ( I checked with Roadranger.....they recommend flushing with Dexron atf.) I probably put at least 2-3 thousand miles on the truck before i figured out my problem. My vibration did go away.
Anyone have any idea what kind of damage might have been done to my trany? Do I drive it till it fails?
The truck pulls a lowboy and end dump with for my excavating company. The truck rarely goes more than 45 minutes in one direction.....should I put an air cooler back it or run without a cooler?
