I was at the local PepBoys store and I came across a "Slick50 high mileage ATF treatment" product. The main purpose of the product is to recover operating viscosity of the fluid.

So I figured that a higher viscosity fluid does sound like a good idea for the torque converter. So I decided to be adventurous and bought a 1/2 quart bottle.

It has a very thick gel-like consistency to it whereas regular ATF pours about as easy as water. I was only able to use up about a 1/4 quart in the fluid resovoir. I managed to pour another 1/4 quart down the transmission dipstick.

So then I put the car in gear and cycled the shift lever from Reverse > Neutral > Drive > Neutral > Park a few times while holding the brake.

Then I went out for a drive. Car sure felt a lot smoother on acceleration especially coming up through 2nd gear from 2000-3000 rpm. In that range, there is typically some torque converter slippage where my car tends to bog down on acceleration until past 3000rpm. Now for the past 3 drives after the treatment, the car pulls up through the low end without any obvious sluggishness. This might just be a phychological effect on my part, but the 1-2 upshift seems a bit firmer too.

The fluid capacity is 10 quarts for the transmission. I added about 1/4 quart of the ATF treatment. The treatment I would guess is about 10 times as thick as the basic fluid. If it all mixes well, I would make a really rough guess that the entire bulk fluid viscosity in the transmission is up maybe 20%. I really don't know if this is sound scientific reasoning or if I am just imagining things.

At any rate, my transmission feels a lot better.

Any comments appreciated --

 

Sounds promising - I'd be interested to know if anyone else has any comments. My 95 SE Auto has 114k, and although the tranny is still strong, it has a few hard shifts, etc. I'd be interested to know of anything to improve performance and more importantly, lengthen the life of the tranny.

 

I haven't used it but I would like to add my opinion, if I may. The last Slick50 additive I used was back in the early 90's in my first car, my camaro. A few months after the oil 'treatment' my engine quickly started going downhill. Luckily we had a friend of the family who was a mechanic. He helped me through a lot of the trouble. Anyways, I take this view of additives, except for occadional, fuel sytem cleaner/treatments; All these companies have similar ploys, this product does "this" because the regular "stuff" you use doesn't do "this". Why wouldn't the manufactures of transmission fluid, synthetic oil or whatever, make the best product that does all of "that stuff". Oh, I know, they don't have the special secret chemists and automobile experts that the additive company has, or better yet, those companies are in cahouts with the automobile repair places and automobile manufacturers to keep people going to repair places and buying new cars. Until someone creates a product that can "regenerate" metal, plastic and rubber, I'll stick to a good maintenance program with good standard products and forget the additives to my pocketbook. Thank you for listening to my rant if you read this. Hopefully I conveyed my point.

 

i agree with you....i think these product do more for hiding the damage or problem than fixing them. Nothing beats maintanence and a good quality oil.

 

Um, there is no fluid resevoir for the auto trans. The only way to put fluid in is through the dipstick.

 

Yeah, maybe his steering is smoother than ever now.

 

O.K. My mistake --

I don't think I did any harm to my car. The service manual specifies ATF fluid for the power steering resovoir. In my confusion, I was thinking the resovoir was an alternate fill point for the ATF.

Steering doesn't feel any different.

 

Do a search, I asked about this not to long back and the responses were not to use it.
