Re: [Chrysler300] Transmission shift points

["Jean-Yves Chouinard" <jymopar@xxxxxxxxxxxxxxx>]

Hi Mark
I find that if I follow the Chrysler Service Manual throttle linkage adj. procedure, I get exactly what you are describing;  too early upshift to my taste...and no down shift unless I'm almost at a dead stop. I'm not a trans. expert so I'm not aware of any other way to modify the shifting of the trans.
 So what I have been doing  to solve the problem is to "modify" step 4 of the adj. procedure: instead of "moving forward the trans. lever against the stop", I move it forward but not quite against the stop. Then I take the car for a road test and if still upshifting too early, I "bring back" the trans lever until I get the shifting the way I like it. Just watch not to bring it back too much as it will cause the opposite, the trans will not up shift at all or "kick down" will engage too easily.
 I don't know if this "backing off" the adj. is a result of wear in the trans. but most all the cars I have had, I would need to back off the adj. lever somewhat to get the desired shifting. 
Hope this helps.
Good luck!

  Subject: [Chrysler300] Transmission shift points


    

  Hi guys,

  This weekend I'm working on my 300H getting it ready to drive to Myrtle Beach in March. I had a little transmission fluid leak so I replaced that little o-ring on the shift cable, and replaced the internal filter screen. While I have the pan off, I thought I'd ask how can I adjust my shift points. The car shifts too early. The 1-2 shift happens when I'm going about 7-10 MPH and the 2-3 shift happens at about 25 MPH. I haven't seen any coverage of the adjustment in the service manual, except the throttle linkage adjustment. I've checked this adjustment several time over the past 7 years, but that doesn't seem to change anything. My 64 300 shifts just right. As a matter of fact, when I put my foot into it, every shift snaps me back in the seat. I need my H to do the same thing.

  How do I make the adjustment? Can anyone give me some detailed instructions?

  Thanks,
  Mark Souders
