The shop foreman let me walk through them doing the tranny service, and I winced when they dropped the pan. I didn't want to see what the fluid would look like after about 55K-miles.
Well, it looked just like the stuff they poured in. Like brand new!!
That gave me a comfort level with this particular interval.
The service interval on the previous hydraulic .3/.4 trannies is the 30K-mile mark. Not sure which tranny Stu is talking about, could it be the .4?
