Getting the 722.3 Trans to Shift Smoothly

Good Evening BenzWorlders,

I wanted to share a triumph I came across recently. Since I purchased my 95 E320, I switched the existing Pentosin ATF over to Liqui Moly Top Tec ATF 1200. I did this for two reasons.

1. I love Liqui Moly and am very impressed by the results I've gotten from it.
2. The transmission was a little hard-shifting for my taste, and I wanted to find a way to make it smoother.

Switching to Liqui Moly and their ATF additive helped a lot, but it was still quite harsh for my liking. Yesterday, I decided to go out on a limb and try a different product on the advice of a fellow Benz nut. I performed another trans oil change, this time using Amsoil Signature Series ATF. Well, all I can say is that this did the trick. If I'm being honest, I was actually kind of sad that the Amsoil worked better than the LM, but credit where it's due, the trans now shifts butter smooth.

If any of you have been struggling with this, and love your car but what it to be a little smoother-shifting, I would try Amsoil Signature Series ATF before messing with any shift improvement kits.

I still fully intend to use Liqui Moly for all my other lube needs, but this trans seems to like the Amsoil friction modifiers A LOT, so that's what it's going to get.

Happy Motoring.

Liqui Moly Titan ATF3000 is the ideal replacement being Dexron 2D, followed by Titan ATF4000 (Dexron 3h)

My bad, brain fart. Yes, I meant Fuchs.

Titan ATF 3000 (Dexron 2D) is the ideal fluid.

I find that the trans shifts "crisper" and faster. Smooth usually means more slipping a.k.a. wear and tear.

We describe the same sensation in different ways.

When I say smooth, I am not referring to how a Buick LeSabre feels to drive. It doesn't feel slushy and inert. Using the LM ATF 1200, and even more so with the Amsoil, the shifts are much better damped, and there is less hesitation to shift. Previously, there was a bit of a hesitation before upshifts. This hesitation is harmful, as clutches, and then the torque converter are under unnecessary load.

Moreover, this type of shifting is not conducive to fuel efficiency because it affects a driver's confidence in the gearbox, and they make changes in their driving style to compensate.

Also, if you know of how to get the oil here in the US, let me know. I'm open to trying it, though I don't know of any distributors for Fuchs or this particular oil at all.

I thought the M104 engines (300, 320 & maybe 280 too) were mated only to the 722.3 and 722.5 gearboxes, not to the 722.4.

Or have I got it wrong?

No, you are right. I just assumed the OP had made a typo.

6 cylinders and up always got the 722.3 box at least in the gasoline versions. The only exception is the OM606 6 cylinder diesel used in the very last year or so of W124 production. That one uses the 722.4

And the 722.5 that, in my opinion, is much underrated. Mine's just been rebuilt after 420k kms by an outfit called Mackie Transmissions in Glasgow. Apparently - I haven't got the car back yet - it's working like new.

Sorry to drift off topic but I'm greatly looking forward to taking delivery on, er, Friday the 13th!

You got it wrong!

The M104 engine was mated to a 722.4 transmission in the ‘96 Merc SL 280 r129 roadster. What’s makes you think the M104 engine was never paired with a 722.4 trans to begin with?

I think this is covered above; the general consensus being that the 722.4 was never twinned with the 6 cylinder engines. Although, as I said, the 280 is not familiar to me.

Anyone else going to chip in?

There's a 320SL on BaT right now that claims to have a 5 speed automatic. US model car.

The 1996 124's in at least the uk had 5spds. Yes I said 1996. They were some " final edition" or something.

What is more important to me is what the update is after 2.5 years of running an experimental fluid. How many miles have been driven and what is the outcome?
