Thats lot of money the dealer said to change the fliter and fliud again and see how it does so next pd i wll change it again.

I agree. I think that's exactly what you should do.

I can only tell you how I made the transition. I pulled the pan, replaced the filter and refilled the trans with about 3 qts of synthetic ATF. Then I pulled the lower transmission cooler line off of the radiator and attached a piece of hose to the line and another one to the radiator and ran them to a one gallon container. I started the engine and let the container fill with oil while I poured an additional gallon in the fill tube, then turned off the engine. I then topped up the trans with synthetic oil. The entire process took 11 qts of synthetic ATF (on my '99 Chevy S-10).

One tip:
When you unbolt the pan, loosen all the bolts on the pan about 6 turns. As you loosen the bolts you may have some oil start to come out. Try to direct the oil to one corner and remove the bolts in that corner and slowly lower the pan after spilling enough fluid into a large drain pan, to do it comfortably.

It doesn't hurt to mix petrol ATF with synthetic ATF though. Although, if you have a pre-'99 Chrysler product, they recommend removing all Petrol ATF as their transmission have been found to work much better with the synthetic.

wavery, this is exactly the method I used on our Voyager and have had great results - so far. I did use Chrysler 4 (full synthetic) and a new filter. It has worked for me and saved a tidy sum of money too.

Chrysler claims that their warranty $ on their transmissions have dropped significantly due to the use of synthetic ATF. The new owners manuals call the ATF "Lifetime", meaning no service required over the life of the vehicle (whatever that means :p . I suppose if the trans goes out, the vehicles "Life" may be over).

A lot of vehicle manufacturers have now switched to Synthetic ATF and motor oil. GM is looking at recommending engine oil changes at 10K miles on synthetic motor oil.

I used to change the oil filter in my Ranger every 5,000 miles, top off the crankcase, and then the whole oil and filter every 10,000 miles.  I did this on the advice of a reputable mechanic in the area.  That is what he does with his own vehicles.
Our new to us F 150 has only about 12,500 miles on it.  When it gets to about 20,000 or so I think I will switch to Mobil 1 again.
As for the trans, its first service is a long ways off.  I don't drive that many miles in a year with my truck.

update on my transmission, after i got home from work put the van in the grage and took the pan off and there was the fliter sitting in the pan!!! so there was no metal in the pan and the fluid did not smell burnt so new fliter and i made sure the rubber o ring that comes with the fliter was up in the hole. i also bought a Tech manual for the 4L60E i got the manual from PATCS SPEED SHOP i order it from there web site. i hope this was it it seem to do ok.

Good find. I thought that might be the problem. Good thing you caught it before you burned up the trans.

well now i don't have to spend $ 1600.00 for a new Trans. :-()
