Liqui MolyATF Additive | 250 ml | Oil additive | SKU: 5135

Two tubes of this product did help my transmission out quite a bit. I think this product is better than Lucas or Seafoam transmission additives.

Exelente producto

Exceptional performance.Added to both trans fluid at change, and power steering pump.A strikingly noticable change in sounds and performance in less than 100 miles of driving.

Buen producto

This product did its thing and works very well

Bien

Me agrado. Ya que me lo recomendaron y tenia problemas con mi transmision, ya que en las subsides no me hacia el cambio de 4a. A 3a. Se patinaba y tenia que desacelerar para que hiciera el cambio. Use este producto y afortunadamente trabaja bien mi transmision. Es algo increible. De verdad lo recomiendo. En lo personal esta trabajando sin problemas. Saludos.

My ML350 is now 11+ years old and had developed a transmission "shudder". If I was going up a hill at local town speeds (35-45mph), it would make this shuddering vibration instead of downshifting. I could almost predict where and when it would happen.The first thing I did was do a fluid and filter change. Now I love Mercedes, but they marketed the 722.9 transmission as "filled for life" which is a crock of BS. When I drained the fluid, it was BLACK. Not good. I replaced the filter and stand pipe and, using the air compressor method pumped in about 5 liters of new fluid. Because my model doesn't have a drain plug on the toque converter, you cant get it all out unless you do a rather complicated flush. I figured, I'd do this change, then do another in a few thousand miles. It seemed to be smoother after doing all this (could be my imagination), but the shudder remained.Well, that fluid change in a few thousand miles turned into 2 1/2 years (best laid plans, etc!). All this time, that annoying shudder was there. So, a few weeks ago I finally drained and replaced another 5 liters of fluid (just a little brown this time), and I added the entire tube of LiquiMoly ATF. After driving for a day or two, the shudder is completely gone and she shifts like butter! Like the day it was driven off the lot! Now I realize this is anecdotal evidence. It could have been that the second 5 liter fluid change lightened up the fluid enough that it cleaned itself out or something, but I am chalking it up to the LiquiMoly. It was too dramatic a change for just changing half the fluid.Your mileage may vary, but I am sold. It gave my transmission new life!
