1994 K1500 ATF?

[renegade_987]

Hey guys, my cousin and I are going to be changing the ATF in his 1994 Chevy Silverado K1500. Not exactly sure on which transmission it is, I just know its a 4 speed auto. Has a 5.7L if that makes a difference. I know that it was originally spec'd for Dex III, but would using Dex VI be better? What brand should I use? Also, does anyone know how many quarts would be needed to do a pan drop for the fluid change? Thanks!

Yes,yes use DEX6

Maxlife.

Dex6 is the only spec supported by GM. I used it in my previous Regal and liked it. Currently I'm using Maxlife in this Regal and its OK... I think Dex6 is still better.

Valvoline maxlife!

Ive used maxlife in mine since 165k when it was first changed out. Had it changed again at 190k with maxlife.

So if we choose Maxlife, that would be the Dex/Merc (Dexron III) version, correct? Will that work as well as a Dexron 6?

All MaxLife is the same. I run it in my 1990 K1500. No problems here. My truck seems to love it. I'd also consider going to Napa or another box store and adding a bottle or two of LubeGard Red.

Also look into the "corvette servo" for the 700R4/ 4L60. Firms up shifts without being obnoxious. I'll be putting one into my firebird; the part is only $15 shipped.

I did a little research on this and for $12.41 on Amazon we might throw one on. Is instillation easy?

Use Castrol Dexron VI. It's on sale at AAP for $4 this month.

Most GM transmissions don't have a drain plug, but you can get an aftermarket pan that has one.
