Flowdrip,
I am not sure this helps but I had the hard first shift and the nice 2nd-3rd flair when cold especially frustrating when merging. I put in synthetic oil and new filter this weekend and the hard shift is better anf the flair is gone. I think I will adjust the vacuum on the hard shift to see if I can get that smoothed out.
hope this helps you.

I'll try that the fluid change this weekend Martin, It's a helluva lot cheaper than rebuilding a tranny!

I have seen this comment a few times, but am not sure what you are referring to. I am aware of the cold shift delay for the cat. to heat up..blah, blah, blah , but how does the tranny react during a "flare" and how does it feel from the driver's experience when it happens? Is this another version of the delayed shift or is it felt like an abrupt change at the end of a longer than usual stretch of acceleration instead of a smooth and almost unnoticeable change?

my understanding of a flare is the tranny trying to shift for a long period of time past where it normally would. As a driver it feels like it needs to change and engine feels like it does not have much power but it just stays in the gear, as soon as you release the gas pedal slightly it will change into the next gear and loads of power again. I hope that is what others consider a flare sure does make for an interesting thread if we all think it is something different.

I consider a flare to be when the transmission attempts to shift and the engine revs out as if the trans is slipping. The trans eventually catches and the gear changes however it takes longer than normal and the engine revs out in between.

Mattman, That was a much better description.

Sorry for the delay, but I just had the K1 Spring Kit installed and it solved the trans flare problem that I have been fighting with for over 16 months!!!!!!! It cost all of $2.26 from the Benz Dealer. This car has never shifted and driven as well as it does now.

A special thanks to Joe P. and Gilly for the information that they provided. I was ready to give up on the car and sell it due to the trans flaring, but now I would not consider parting with this car. May she live long and enjoy the roads.

this is great! What is the procedure to intall it? Do you have to remove the valve body?

esm6869 · #24 01-31-2003, 10:46 AM

The valve body does not need to come out. You just drop the pan and remove three screws from the end plate of the K1 accumulator. Pull out the piston with the spring assembly, replace the two springs. Check your seal rings while your in there and put it back in. Put the end plate and the pan back on and the install is finished. I went further and made sure the pressure to the vaccum modulator was what the book called for and had the cable adjusted. At near two hundred thousand miles, this car shifts better than any of my vehicles!

Thanks! This is good news. The trans on the '91 300E (200k) has been adjusted for first 1-2 shifts to compensate for 2-3 flaring. How is the shift quality now, especially the 1-2 shifts?

You said "Check your seal rings" would you mind explaining this a bit further. What woul I be looking for and what do I do if there is a problem?

Anyone have the part number for the K1-spring accumulator kit?

My car is 1995 E320.

Thanks

esm6869 · #27 01-31-2003, 12:10 PM

I don't know what number trans the '95 E320 has, but the spring kit that I used will work on the 722.3, 722.4 and the 722.5. That part number is 126-270-44-77.

Again, a big thanks to Joe P. at Behind the Star and Gilly at Zimbrick European for pointing me to the spring kit!!!

95e320 · #28 01-31-2003, 02:00 PM

That's great! I think 722.3,4,5 were the only transmission used in 6 cylinder gasoline engines in W124. I just called my dealership and of course they never heard of it. They will order it for me, however.

Now, Are there any instructions that come with this kit or can anyone give me a quick note as to the procedure?

Thank you

Instructions do not come with the kit, only two springs and a couple of plastic pieces. Very little in parts, BIG OUTCOME though.

That's great if that kit will solve your problems, I have just had my trans apart for a similar problem and due to the car having been driven for quite a while with the flaring the bands and clutches were all shot.

Just got the car back with a reconditioned transmission and it's like new again.
