hello and please help

car is '92 300e, 167k and very well maintained.

the other day i started car [cold] and shifted into drive and nothing happened.

again the following day the same thing happened. yesterday [car was warm] i started and shifted into reverse and nothing happened.

i was patient and didn't force anything and in just a few seconds when i shifted again everything did what it should. wtf?

anyone have any thoughts or ideas? stevebfl, gilly, gsxr, larry bible, aaron?

i'm taking the car to florida in a couple of weeks and would like to not have to worry about this.

thanks.
peter

If its the b2 I wouldn't go anywhere with the car.

How is the fluid?

The B2 can be sticking or has dirt in it.... ...intermittant problem
Fluid/filter change is a good idea ,making sure to do the converter too
Change it Hot and let it drain real good.
Clean pan Spotless before reseal..

hey arthur and yal

thanks for your input.


in taking a another look, the gear shift lever itself is moving more than IT should [fore and aft]. i have to pull it past [a little] reverse and drive to engage tranny.

it seems like it is loose, it has extra back and forth play in it. can the shift lever be adjusted or tightened up?

everything shifts smooth and is quiet and nothing is slipping or hard shifting.
rear main seal and tranny was overhauled [preventitive] last year. i do the transmission filter and service about every 30k miles.

thanks

peter

You have a worn bushing on the trans selector arm/link.
Do a search .. short $$$ and a DIyer job...

Arthur:

Familiar with the B2 info at the Ritter-Easley site. Maybe you can clear something up for me.

The article indicates the B2 problem was resolved in the late 80s. The original poster in the thread has a '92 model. Would his MB have come with an improved B2?

It would be interesting to know what yr. MB came out with the improved B2.

Thanks.

The rebuild info I have [ fromwww.transonline] indicates there were b2 seal and bushing/sleeve mods right up to 722.369s [ late 124s-94/95s]
That site was great and free , but they finally dropped the free bit..
The later improvements , I believe, were the type of seal on the piston itself,[ teflon replacement, I think], whereas the early ones actually had piston breakage/failure.
both with the same result...except the later ones would stick, causing an intermittant problem, whereas , the old ones just broke into pieces and you called a tow truck...
Tranny guys here prolly know exactly.......

While we have tranny fluid changing post interest here , here are some thoughts:

When I change out the filter/fluid, clean out the pan , drain converter, blah blah....blah..button it up, etc..
I then cut the old filter open and take a good hard look... and wow... some of them are BAAAAAAD , with everthing from clutch material to metal fillings.. so..
If the filter was not too bad , I let it go and consider the job done....
But if it is bad, I run the car for a week or two [ maybe 300/400 miles] ,
and then I drain it again.
...both the converter and the pan...and I take the pan OFF AGAIN [ you got a new gasket, so no sweat here].---Not just the drain plug. [ this allows you to wash the pan again.. and there will be stuff the first fluid change carries out of the valve body.clutch surfaces, and cavities you did not get the first time]
I do not change the filter this second time , as I feel it has not had a chance to catch much yet.
The cost of 7/8 more qts of fluid are cheapo insurance and so far , I have saved a few trannies with this extra effort...you just can't over clean your tranny .....

arthur
thanks. how do i access it?

Get under there and look up..
You will see the rod that hooks to the shifter and goes to the tranny.............

Yes the bushing is likely and it is a simple job.

If the bushing is the problem, it is because you aren't moving the shift valve far enough when the shifter is in the "D" or "R" position. This is easily overcome for diagnostic purposes by just moving the shifter till the gear is engaged. There is no way the lack of a shift bushing can keep the car out of gear unless the rod has totally fallen off and in that case it would never work again and you would notice nothing happens when the shifter is moved.

Pull the shifter past the gear and it would engage if the bushing is the problem. The only gears you can't do this with is "P" and "1" or "2" whatever is the lowest gear. because of this be sure you are in Park if you don't set the brake.

steve
thank you for your reply.

you are correct, i 'would definetly notice if nothing happened when shift lever is moved'.

arthur-thanks again to.

it is definetly that bushing, i have those symptoms.

i will make the adjustments in 'my' shifting until i fix this bugger.

i'll probably just have the tranny serviced while i'm at it.

again THANKS!

peter
