Tom - awesome help!!!! I have a 1988 MH with a Cummins 5.9 and a 4 year old factory rebuilt AT545....Only has about 6k miles on it.... I have no ideal which fluid is in it, as the replacement was done by previous, now deceased owner... Your thoughts, please........
Pass42,
Sorry, I thought I answered this one but maybe not. I would take a sample from the transmission and send it in for analysis.
If the analysis shows that a transmission fluid change is needed, then I'd recommend you switch to TranSynd or another TES-295 fluid for the long run since it will extend the life of the AT545 transmission.
