I was hoping to report to all of you that my 5 speed in my new 96 420 was now shifting perfectly, but I'm sorry to have to report:frown it isnt quite right yet.

When I got it there was a long delay between shifting the lever into P and actual engagement. I hoped naively this might be a fluid issue so it got fluid, filter and connector right away. (no sign of leakage into the cable) Didn't change shift delay a bit. Except for the delay, the shifting was smooth and quick. Then a couple weeks ago I started to get a harsh 2-3 shift which got worse quickly. 3-4 was a bit harsh in short order and 4-3 thumped and then went into a false neutral until I shut off the car and restarted. This is on a 120k mi. car owned all its life by an old man in Phoenix. I certainly did not expect much wear.

Some excellent DIY articles (thanks MAVA and G-AMG) convinced me I should replace the pressure spring, so I tackled it last week. I also replaced the three shift overlap sleeves with the o-ringed replacements and since I was in it that far I replaced the conductor plate as well. Shifting under way is back to being smooth and quick again, but the 4 second delay between the P-D shift and engagement is still the same.

What causes this frustrating delay and how do I fix it?

Thanks for any help and suggestions,

Mike in ABQ

Yes, it does this in Winter and Summer modes. It also does it when engaging reverse, but not as bad. What I notice with reverse is that when I shift from drive to reverse it engages reverse like I expect, then it drops out and is not engaged for about a second, then it reengages and works like expected. The rest of the functions of the tranny seem to work very well. The shifts are smooth and consistent at high or low loads.

I have reset the adaptations with the kickdown switch method.
