64 & mostly clear in upstate SC, still hoping to get satisfaction from Ford on transmission stutter. At 54,000 they recommended a flush stutter is back now at 92,000.

Thumbs up on the 64* :) - Thumbs down on the transmission issue :(

what the recommended fluid change at?

we sprinters live with a thing called RST.......rumble strip tremor.....closer to the change period, the more pronounced it gets....its not a problem per say just a little thing about the Sprinter...

Ever since I got the Silverstar I've been changing the fluid every 25,000-35,000 miles. In addition, right before changing the fluid I'll dump a can of BG Quick Clean into the transmission and then drive it the 20 miles to where I have the fluid changed. At the change, they replace a little of the transmission fluid with a (me supplied) can of BG ATC+, which is what Silverstar recommends. Silverstar also recommends that if the RSN (Rumble Strip Noise) returns between changes to just add a can of ATC+. I haven't had to do that yet, probably because of the initial ATC+ at the fluid change, and the relatively frequent fluid changes.

I've got 294,141 miles on this transmission, so it won't be too much longer before I know if it's working.

I remember many years ago when the sprinters first came out the manual said transmission change and 70,000 miles I believe and that was it never said another word but doing it again

Guess our Transit is the only one with a sprinter transmission, lol. Cause that sounds like what's going on with ours. And I wouldn't mind a regular flush/change every 35k...but it is a sealed transmission not supposed to be serviced until 150k....

It's worse than merely never saying another word about doing it again, it is very explicit, both in the Owner's Manual and in the Scheduled Maintenance Manual:

From the Owner's manual...

From the Scheduled Maintenance Manual. where it has just the one page for recording all of the transmission maintenance for the life of the vehicle...

Then they came out with a TSB that said change it every 60,00 miles, and a year after that came out with one that said every 50,000 miles.

Well, it won't hurt it to change the fluid early. Once the fluid starts breaking down, it goes quick, and shortens the life of the transmission. If the transmission fluid gets too hot, it begins to rapidly break down. RLENT has a temperature gauge for both his engine coolant and his transmission fluid in the transmission, and it was surprising to see just how much hotter the transmission fluid can get than the engine coolant when climbing grades in the summer (at 75 ambient or hotter). Grades in the Appalachians and the Rockies, and elsewhere. The engine coolant tempt might be 200-210 F on an uphill grade, but the transmission coolant might be 260 F or hotter.

ATF is designed to operate and perform best within the range of 175-210 F. For every 20 degree increase in fluid temperature beyond the normal range, the life of the fluid is cut roughly in half. So if you do a lot of towing or you are routinely loaded near the max GVWR, you should probably change your fluid at least at half the normal interval, if not sooner. That or you should consider an external transmission cooler.

If it were me, I'd change it out every 50,000 miles and I'd use a can of BG ATC+ in every change.

Tranny guy once told me drain & fill with filter every 50K. Never flush
I do mine about every 50,000 and I've never done a flush...I also do the rear end fluid at the same time....thats a bit of over kill and its only about $50.00 but hey here I am at 1,000,000+ miles and same rear end components hasn't ever been touched....it must be working...:p
