engine oil in this truck has been changed almost every month for 2 yrs...filter every other month....i just feel like changing trans fluid for once.....lol. access to oil is no problem for me...

From what I've heard, the only time that you have issues after changing trands fluid is when the old fluid was totally brown and burnt. The theory was that the old fluid coated everything and didn't allow the new fluid to work, so the trans slipped. This could just be one of those old mechanic's tales though.

I've got 125K on my Navigator and never changed it. Was thinking about changin' it to Royal Purple synthetic until I saw how much it was and how much it holds .. I'd never recover the price difference.

Looking at a manual for a 97, it says you use Mercon fluid (doesn't say Mercon V.)

thats what i was thinking....97 is different. asked guy behind counter same question...i repeated to him 3 times 1997....guy doesnt bother really looking just tells me mercon v....DEALERS are stupid people....LAZY .i was getting anti freeze for va 04 expy...that gold stuff....was spending like 50 bucks on 5 gallons and couldnt get right answer from guy....i return from getting fluid ask this guy who i pick up auction cars 4...he says same....********....gonna look this fluid thingy up..

Probably won't find straight Mercon anymore. Mercon V was reformulated a few years back to work for Mercon or Mercon V. Mercon V is all that is sold now and works just fine in both fluid types.

Hmm, I was beginning to wonder if that was the case. Makes sense.

aircagoo I'd check/confirm with the local dealer just to be sure

Regular Mercon trans fluid is designated as Mercon III / Dextron now.
Mercon V is a different product, and I couldn't find a synthetic version of it.

Anyone know if it makes a difference if you use regular or synthetic trans fluids?
