Question Opinions on Valvoline High Mileage ATF?

Just got 8 qts of the Valvoline ATF High Mileage formulae... this does not have the stop leak in it. It is a little more expensive than other ATF... $2.52/qt, but is not a synthetic. Anyone have any experience with this or should I just use the standard ATF? My transmission seems OK at this time with around 200K.

Thanks

I've been wondering myself as I have about 226K on my 87 300D and while the fluid was just changed, I did ponder a thought while at Autozone, back there in the oil and tranny fluid section.

Should I buy the higher milage stuff or not?

I desided not, and bought Castrols dextron 111, I beleive it was.

My brother, a Volvo specialist, told me that to properly change all the fluid you have to get all of it, including what's in the torque converter and the only way to do that is to drain the system and add new fluid several times until it is clear and red.

I used about 4 gallons total before it became nice and red. My method on the 124 was to unfasten the top transmission cooling line ( passengers side) of the radiator and run the engine until the fluid just begins to stop coming out. Shut the engine off and return the same amount that came out. Do this several times until the fluid is clear and just as red as it came out of the bottle.

I'm not fully sure what's in the fluid your considering, I've seen where they include some sort of seal conditioner, etc.

Good luck

I just topped my fluid level off with that same stuff. Before that, I added a quart of Chevron III a year ago, before that I don't know what was in it. So, I have a mix. I wonder what y'all think of that, probably not a good idea, but it was low and thats what I found.
I probably should drain and replace, but I'll add that onto my long list of things to do.....

To get the most old oil out when you change your trans fluid you can pull the return cooling line and run the car after you refill with clean fluid. This will pump (flush) new fluid through part of your converter and all of your cooling lines and radiator. When clean fluid comes through, shut off the car. You can anticipate the fluid level drop by overfilling a quart or so to start.

On vehicles with screens instead of filters, the exhange system at the dealer does about the same job.

On vehicles that have a drain on the converter this is not necessary.

I have not seen the specs and do not know, but I suspect that the high mileage oil/ATF is a product of the marketing dept and not of the engineering dept.

I used the Valvoline high mileage stuff the last time I changed my fluid, I also put some Trans X in it. No change in the first 500miles, although the leaks seem to be slowing somewhat. I used Valvoline High mileage products on my Toyota and was very happy with them, there oil sealed up the valve seals nicely.

Thanks for the feedback. My 82 300D does have a drain for the torque converter so I do anticipate being able to do a complete change. I don't have any leaks either. Would the trans-X product offer me any benefit in this case?

If it aint broke, dont fix it!

I'm leary about putting a magic cure-all elixor in anything.

And I wonder what else it will seal?????

Dosen't slick 50, or some of those space age lubricants, have something for transmissions?

I put Mobile 1 differential oil in my rear end. It has some pretty remarkable lube qualities!

OOPS!

torque converter drain

Its my understanding that all MB automatics have a torque converter drain and that it should be used for a complete fluid change.

Both my 300's have had this ('79 & '87) and my mechanic always drains the converter as part of the tramsmission service. I know this because I watch him service the car. Its nice to have a mechanic that will let you watch everything that he does.

Hey, I let customers watch everything I do, even put a wrench in their hand and tell them what to do.

Now SOME of the things I do really disgusts them when they watch, but...., oh..., wait....., you mean just the wrenching......oh...

Question Where is the plug?

I didn't notice when I had it out while exchanging 603's recently, dont know why I didn't see it.

The opening at the bottom of the tranny, where you access the bolts that connect the flywheel to the torque converter could only be where I would find the plug, correct????

There's a small opening in the casting about 1"x2". Use a large screw driver to rotate the TC around till you see the plug. It's small, about 12mm in diameter and takes a 6mm hex wrench to remove.

hello there,
well I don't like dealing with tranny's so I cheat, I have non-towing rigs serviced once every 2 years, and towing rigs serviced once a year. on there first visit to the shop, I'll change out the standard tranny cooler of the biggest one that will fit. I also use synthic lube's cause they do lube better, and cooler. I've also noticed a slight improvement in mpg, using synthnic in the rear-ends and front-ends where 4x4's are the rigs.
