Bad situation.. My brother was in his 2002 CTD 47re, coming down a 4-6% grade in 2nd gear. He had slowed for a steeper section to about 10-15 mph. When it flattened out a bit, he attempted to move back into Drive, and went all the way through to Reverse. Tires chirped, truck died, trans light came on. It started once when he got it pulled over, and he had all forward and reverse gears. Shut it down, and now can't get it into park all the way, and the truck won't start. It will be on a hauler shortly. This seems like a major breakdown to me. Anyone have any ideas what may be broken? Thanks, Colby

 

Ouch --

Could he had simply broken a shifter rod or pawl? Not so sure if it entails an automatic. Probably going to have to come apart.

As to the no-start - there's an interlock device that won't allow the starter to engage and if a shift pawl was "redesigned" it may not be able to quite push a shift rod far enough to allow the interlock to be activated again. But this is a hazard of a guess...

good luck with this one...

Well, either he did overshoot the R and went to P and got to some nice carnage, or he might also have torn a shaft and additionally "redesigned" the shifter linkage- meaning that the position of the shifter does not correspond with the shift lever of the tranny anymore. This can lead to the starter being disabled by the park-neutral safety switch that says that the truck is in gear. You might get by for the moment with shifting to each gear (and possibly some weird in-between gears positions) and check if the starter starts to work. If you lift the shift lever you can feel the detents of the shift lever in the VB- pull the lever as far as possible to the 1-position and then back up 2 detents and try to start- if it does not work, try it with a 2nd detent further up- try again.

Be very careful while trying this because with a malfunction of the shifter linkage the engine could get started with the truck in gear!

If you get it running, and the tranny can be shifted to some gear and only the shift indicator is wrong you will need to adjust the shifter linkage and the indicator after you adjusted the linkage.

You may not have gotten quite all the story. If it made it into "park" then all heck perhaps broke loose.
Otherwise, enough reverse torque generated on engine supports, ect that linkage was damaged either external or internal.

go thru the positions, and try the key.

 

well you cant exactly get reverse tourque when you hit park, otherwise a vehicle would never run, in park the trany locks not the converter there is no solid link between the engine and transmission, essentially you put the trans itself in neutral, it sounds to me like the park pawl is probably broken, best fix, drop the trany go threw and rebuild it and put it back in

 

Dieselboys, think about it. When it hits park. The driveshaft essentially locks though the park assy. That is locked to the extension housing. The extension housing is mounted to crossmember through a support. The driveshaft suddenlly stops rotating. What do you think happens at that point? The reverse torque is trying to rotate the frame of truck. All heck breaks loose.

 

ya thats true but that would not kill the engine, I missread your post, but in his the engine died, therefore straight to reverse is more likely because in that case the engine would feel the direct effect of that, if he went straight to park it wouldn't have died, just twisted and ground alot of steel, and probably broke the driveline, but more likely a park pawl would go first, at least thats the way it was engineered to minimize damage to the rest of the pickup. there for the torque wouldn't be entirly transfered to crossmembers engine mounts ect. there would however be an enitial shock to those particular things, meaning that yes linkages could be bent and so on. But also if that park pawl is broken it would not alow the pickup to start, at this point just rebuild the tranny and you should be fine, not to say that that will be cheap but its the best way to go

 

You can throw a torqueflight trans in park moving above 10mph. The park rod will just "ratchet" on the pawl. It won't actually catch until you're going quite slow. Putting the trans in R while moving forward is a whole different issue. It will attempt to apply. BTW back in the day of the mechanical governors if you had a prob with a sticky governor weight you could often free it up by hitting park for a second or so while moving 15mph or faster. The governor was attached to the rear of the park pawl assy and the vibration would often free up the weights.

 

I think scaring the poor guy with talk of breaking the driveline and motor mounts and tranny crossmembers is a little excessive, don't you guys? If it went into reverse, odds are the clutch pack inside the tranny took a big hit but probably slipped enough to avoid "all heck breaking loose." If it made it to park the pawl would have certainly been snapped off before much of anything else would have broke.

I say, as mentioned above, check to make sure the linkage didn't get a little bound up and move the shifter around to see if it will start that way. If that doesn't work, you've got to figure out what electronic component is not letting the truck start. I'd start at the park/neutral/reverse switch at the tranny and verify that you are getting proper signals from there. Maybe running a code scan would yield some good information?

Heck, I accidentaly moved into reverse when going 40 MPH in a 92 ford... It killed the motor, I popped it into neutral and restarted it and went on my merry way for another 5000 miles before I sold it. Yeah it's a different animal than the Cummins, but it's worth mentioning.

Good luck and keep us posted!

 

Alright, thanks for all the interest. Sounds like he made it all the way to park. There is a fork at the top of the tranny, and that was way out of alignment. The shift linkage was also bent. The park pawl may have been affected, but it was not broken. So all the bands were loosened to re-align everything, and the affected parts were attended to. New filter, new fluid, band adjustments, etc... Everything feels good, except, when starting from a standing stop, the trans shifts to second, then back to first and back to second, and then it shifts through the rest of the gears fine. It's going back on Monday to be adjusted. Colby

 

My '96 used to hang in second gear unless I downshifted to neutral first when coming to a stop. Didn't do it all the time, just seemed like every few months it wanted to show it's butt for a week or so, then it would go back to shifting normal. I accidentally hit reverse more than a few times, but it never seemed to hurt anything.

On a side note, I used to have a '64 Sport Fury with the early TourqeFlite tranny. Push button shifter on side of the dash, push button heater controls on the other (really dumb idea). One 40 degree morning at 4 am and still half asleep I went to turn the heat on. Hit reverse at 45 mph. I swear the rear wheels came three feet off the ground about ten times. Scared me half to death. Started the car and drove off and never had another problem. Ten years later I still see the car at shows around Central Florida and the owner says he has never had any tranny problems. I've always been a die-hard Mopar fan and their tranny's are one reason why. Funny tho' that the King of all motors, the Hemi, couldn't do to a tranny what a de-tuned Cummins can.
