Replying to: underpressure (Aug 04, 2009 11:36 am) Yes that does sound like a timing chain actually.   Mercedes 190D -- sounds and looks like a worn out piece of iron that never had maintenance, injector pump timing or fuel additives. That engine is "nailing" and begging for some mercy. Replies to this message: fintail (Aug 04, 2009 4:45 pm) Mr_Shiftright (Aug 04, 2009 5:12 pm)

Replying to: Mr_Shiftright (Aug 04, 2009 2:55 pm) You don't like the sound of rocks in a blender?   It's idling too slow in gear, too - that's why it stalled. At the least it needs some diesel purge.   But it fits the old stereotype to a tee. Replies to this message: Mr_Shiftright (Aug 04, 2009 5:12 pm)

#2201 of 2231 No upshift to 4th gear when in d position by benzsilver Aug 04, 2009 (5:49 pm)
I have an '84 cdt. I had put a new groumet on the upper link of the transmission linkage. I had bought 2 new groumets, but after the tussel to replace the upper one, I decided to wait on replacing the lower one which connects directly to the floor shifter. It appeared to be fairly snug at that time( a year ago) Well i had some time on my hands last week so I decided to replace the lower groumet on same shifter since the shifter seemed to have some additional play in it. Again I tusseled at replacing the groumet. The tussel is with the design of the keeper which is an improvement over the well-known cottarpin designed keeper. I got it all done and took the benz for a spin and I noticed the trans never shifted to drive althoough the indicater was pointing to D. It seems I have to manually shift from S to L to D toget the gears to change. P, R and N work as they always have. Whats going on with this? Comments, suggestions would be appreciated Replies to this message: burdawg (Aug 04, 2009 9:02 pm)

Replying to: benzsilver (Aug 04, 2009 5:49 pm) I'll wager that with the new grommet the adjustment is just off enough to keep it out of overdrive. When you shift it manually the inertia of the upshift may be enough to move the shifter a little bit more than when you just start out in D. Try starting out in drive and wiggling the shifter back and forth to see if it will go into overdrive when expected.

Replying to: Mr_Shiftright (Jun 24, 2008 5:54 pm) Mr Shiftright..I recently replaced the back groumet (transmission) on my mb300 cdt after having replaced the front one a year ago. When I replaced th front one the trans continued to work well, however when I replaced the back one, the transmission will not go thru its changes to 4th gear. P,R,&N seem to work as they should. I can get the gear to change from 1s t to 2nd by placing the gear lever in N then moving selector to L, the to maybe get it to go to 3rd gear again moving selector back to N the back to D. It sometimes down shifts to L but generally will stay in 3rd, however if I move the lever back to N then back to D, it does not go into D or 4th gear. If I have to stop, I have to repeat the process. I know this is probably good for the trans. The trans has never given me any problems until I changed(replaced) the back groumet(Linkage connecting the floor shifter) I have not been able to find any instructions as to how to adjust the linkage. Please help. billfletes-srlive.com
#2205 of 2231 adjusting auto trans, floor shift model by Mr_Shiftright HOST Aug 23, 2009 (7:15 pm)
Loosen the locknut and disconnect the selector rod from the bottom of the selector lever. Then place the selector lever on the transmission and the shift lever in the vehicle to Neutral. Then adjust the length of the selector rod so that it can be reconnected without disturbing the levers. Reconnect the selector lever and tighten the nut securely.
