5R110 diagnostic info needed

5R110 diagnostic & repair info needed

Howdy all, I have an '04 E350 with a 6.0 Powerstroke, the 5R110 and big problems

113k miles on the van, 377 since I bought it, here's what little we know


headed into town towing a small utility trailer and the van ran great. 30 miles on the highway, 6-7 miles of stop-n-go traffic, then starting out from a light the van bucked like crazy (probably at the 1-2 or 2-3 shift) the differential began growling horribly and it only had first gear

drove aprox 2 miles & parked at a relatives, pulled the diff cover and drained quarts of busted gear soup. the axles were ok, replaced the rest.

changed both trans filters, fluid was ok, only regular debri in pan


now only first & reverse work and the shifter stalk light starts flashing instead of upshifting to second


I have an elm327 clone, lots of time spent reading here and the barely a clue on how much I need to learn. can't afford an autoenginuity with the ford pack, much less a rebuilt transmission...


can anybody lend me a clue? or know of an honest transmission shop in San Antonio TX?


thx

just tried that again & drove around the block. it upshifted around 8 mph a couple of times but no second shift. parked & checked codes, elm can't read trans codes so no useful info

tried driving around the block a second time

upshifted at 8ish, tried to upshift again at 12-14 but bucked then the transmission locked up and the rear tires slid/chirped. (at least it didn't destroy the differential this time) shut it down, shifted into park, waited a minute. cranked up again and first/reverse worked ok but back to no upshift at all

some progress

near as I can figure from this post at theDieselstop what happened was the rear segment 2-3 shift (clutch e) didn't, which equals a 2-1 downshift, and the van's inertia shredded the spider gears. must not have been the first time that happened!

which also explains the tire chirp after the code clearing battery cable removal. fortunately the new differential survived and now I know not to do that again (sigh)


pulled the pan again, no significant metal shavings


I've maybe found some error code info in the help files that come with

OBDII Diagnostic ScanTools and code-readers

is anyone familiar enough with that package to comment?


on a related note, does anyone know of a chip/tuner which could read/clear codes, allow for manual shifting or skipping gears that require an inoperative clutch pack?

(the solenoids tested ok, not clogged, sensors seem to be working)

thx Granny, at least it can still limp around locally with R-1-2

I've got the 5R110W ATSG manual ordered, already bought the wiring diagrams


fwiw, found an honest shop in SA, David Colbath Transmission. he gave me a reasonable price on what he thought the problem would be so I said do it - spent a day on it and then put it back together with a "that wasn't it, my bad, no charge". didn't try to sell me muffler bearings or any such crap.

kinda feel bad he wasted an afternoon on a bad guess, boy do I know how that goes...



I've got an '80 GMC 3500 and a '73 Dodge RV to cover highway towing if a paying job comes along. really didn't expect to be working them again, sure is nice to have backup tools appraised as scrap metal
