I have been struggling with operating problems on my '97 D1. Rough idle. Over-fueling at idle. Intermittent cam position sensor problems. O2 sensors dropping in and out. Intermittent speedo. All kinds of crazy stuff.
I have split open harnesses, replaced sensors, etc, etc ad nauseam.
Two...
Time for the perfunctory update. The truck is now at 272k miles. The rebuilt steering box was done about 51k miles ago. I have found that on very hot days the seals seep a little after shutdown but running at pressure it does not leak.
I have to say I am astounded that the rebuild has held up...

I was thinking thief, slime, scum or butt-munch was a simple enough description. LOL
I have addressed the engine oil lines and am about to do the same for the transmission lines.
Using the original lines the old hose and crimp area were cut away. The ends of the steel lines were cleaned and a brass hose barbed sweated to the end. The barb was a generic brass fitting with the ID...
Bumping this thread. Any luck with making new lines or just take the hit and buy lines from the usual suspects?
I have the crimping tools to put new hose between the hard line sections. I am wondering if the known failures are in hard line fatigue or flex line leaks.
So the fluid was very high. Nearly 1.5 liters. The dipstick then showed the correct level at cold idle.
Two or three laps around the block and the gearbox returned to its former normal behavior.
Lesson Learned: Don't assume the fluid level is correct regardless of who did the service.
Sorry...
I also found the section of the Workshop Manual covering the automatic gearbox. That should help.
After reading it there are a number of problems that can cause the limp mode (3/4). Most point to the regulator. First things first.
So far the stall and manual shift tests passed.
Interestingly though, probably what I get for letting others do ANY service on my vehicle, the transmission fluid level is quite high. I intend to siphon it down to the correct level as well then take it for a drive.
I figured that there has been a failure but I am interested in determining what failed.
I did find a ZF 4HP22 powertrain manual with basic diagnostics in it. I'll start there.
OK, a typo. That was supposed to be "...slow/no...". Sorry.
Recently the transmission on my '97 D1 began exhibiting a downshift problem.
When slowing to a stop it only shifts to 3rd. It will shift to 2nd or 1st if the selector is moved.
I am not an automatic expert but am wondering where I...
I am interested in the results. I have a '97 D1 that is due for shocks (almost 270k on the odo). The ride is getting weird and harsh as the shocks wear. The rears feel OK but the front are due.
'97 D1. Stock, stock, stock.
An update:
The box was dripping a bit but suddenly stopped. I am assuming it was caused by debris in the seal. That would have come from inside the system so now I am considering a filter or screen on the return side of the system.
Depends on the plastic. 3D print in nylon requires a high bed temp and a high extruder temp. Since I now have 3D printing in addition to CNC I am making all sorts of low stress parts. Like the switch panel in the armrest that crumbles. Maybe I'll put that on thingiverse.
The rings are teflon. Softening point and melt point of teflon (as you know from the Bowden tube feed on most printers) is higher than most materials available in filament. If I recall correctly the melt point is above the decomposition point for teflon. The warming and sizing steps seem they...
I'll need to look at my notes but I bought some sensors that are either D2 or Jag. I only had to move the pins from the included plug to the originals from the old sensors.
Plug-n-play baby.
