1995 E40D no forward gears
Had tranny fluid and filter replaced a couple months ago. It's in a 35 foot motorhome (F53 chassis). The motorhome is within it's GCWR. Climbing a 6% grade at 3,500 rpm, little more than half throttle, like all the other climbs. 80 degrees out. Engine temp was on the letter "R" on the word "NORMAL". All of a sudden my engine redlines as if it popped into neutral. I let off, put it into neutral, and try "D" again. Nothing. At this point it's uphill so it's naturally slowing down and I try "2". Nothing. Even slower and I try "1". Nothing. Pulling over blocking the right lane on a blind curve on a grade is scary. Had pylon cones out, waving traffic to warn them down a ways, etc.
No fluid on the ground, no slipping prior to this. Any ideas? I have reverse. I see no obvious linkage or electrical/wire issues underneath (from road debris, etc). It's at a shop but I want to know all I can so if they come back with something outrageous I can make a decision. I never pulled the stick, as I was coordinating traffic, highway patrol, a tow truck, etc.

typically that's from a failing MLPS or dirty connection to it.
however your supposed to have reverse and 2nd gear still when shifting manually to 1st or 2nd.
maybe something real bad happened or just the bolts on the shift lever bracket loosened up under the dash.ford didn't put lock tight on those for some reason.

That's completely wrong. There is NO WAY that a failing MLPS or a dirty connection to ANYTHING can prevent all forward gears. No way, not possible.
Something mechanical broke inside the trans. There is no way ANYTHING electrical could cause this.

you skipped the second sentence in the quote.:D
that's what i said just differently lol.
of course when saying "typically" a neutral state all the sudden is from a failed MLPS or poor connection.very common.
however as stated,he's tried manual 1/2 and still nothing.thus not being MLPS related.
