The OP Asked : 'Btw whats the diffrence between the trans yellow bottle and blue bottle? '

I don't know, that's why I was upset when I went to my F.L.A.P.S. and saw more than two colors of bottles.....

It appears I got lucky and used the correct yellow bottle stuff .

I also use that Valvoline Dexron in the red jugs .

Transmission no longer slips after uaing Trams x and topping it off with ATF. However my trans cooler lines are are leaking ATF which is strange.

It sounds like you don't realise that ATF goes through the cooler lines to a portion of the radiator at the front of the car - so it isn't in my opinion particularly strange that ATF might leak from the flexible lines.


It is a very good idea to change these cooler lines for new as soon as possible if they start leaking as degrading rubber parts on the insides of the hoses have been known to end up in the valve body - "that" side of the system is not protected by the transmission filter.


I'm glad you've now got a non slipping transmission - I personally wouldn't attribute the fix to the additive - sounds to me like your fluid was too low. These transmissions are not only fussy for the type of fluid used but also the amount of fluid to which they are filled.

Don't leave that there - I'll take it to bits!

You probably had the shifting issue from low transmission hydraulic pressure from a dirty filter, varnish in the valve body, and fluid leaks from the transmission cooler lines.

Now that you have better pressure, you have better shifting, and also the pre-existing seepage has turned into a more obvious leak.

Check your flexible oil cooler lines that connect to the radiator.
Also check the the condition of the six rubber buffers in the six clamps that secure the rigid transmission lines to the upper oil pan and the transmission support bracket behind the engine.
There could be pinhole leaks in the rigid metal lines beneath the line clamps.

That's a nice article, I notice he neglects to mention that the cause was the rubber gussets had degraded allowing metal to metal contact .

These rubber bushings are still available from M-B and are not expensive, easy to install .

Allowing your engine and driveline to become coated in oil like this is why so many leaks and bad bushings occur .
