Allison Transmission

Go ahead and follow the above advice and throw the dice too. Its only $10000.
If you don't know have a full service done. Now you have a starting point for regular service, which I might extend a bit because of the low mileage put on RV's as a whole. Again full service with Transynd.

There ya go,, our coach is 17 years old with 50K milage. the tranny has never been serviced. the fluid is good, as are the filtrers.

If it ain't broke, don't fix it until it is.

Simply check the level correctly, and see no brown looking fluid, and it doesn't smell bad you should be good to go.

over the road truckers using this tranny usually have no problems with it.

I agree with Ron above. if you have maintenance records as to when it was done last, go from that. If no idea when or if change the filters and fluid out for the transyd. I did mine myself and it wasn't a huge job.

This is obviously not a mh that you have owned since new So, if you don't know when the last time it was serviced, I would go ahead and drain, install two new filters and replace the fluid with Transynd.

What type of fluid are you running?
