Dex VI Fluid Change

I switched from III to VI at 123K (granted only 5K ago) with only doing a pan drop and still drives fine. So theoretically I have Dex 4.5....

Same thing.... im at 3k tho, but It shift a hell of alot better IMO, then again I was at 80k and didnt know when the last time it was changed, wasnt slipping but was really really dark looking and tech said it had a slight burnt smell when draining it
:th_scratchhead:

Up to you tho

I have one ready to replace the wbody store shfit kit in mine and one for my brothers 03.

For all of those asking why he recommended to stick with dex 3 versus switching to dex 6, I will post his email reply so I don't misquote him. Dave thanks for the info and he can help those out with the 04+, as I am not sure which years dex 6 was introduced into the newer vehicles.

Dex VI is a good fluid and supposed to be backwards compatible with Dex 3 which is what came in your vehicles. I personally am not a big fan of switching fluids on a matured transmission and since VI is a bit thinner and a synthetic blend you could run into excessive slippage problems and set code P1811 if the pcm cant compensate enough. Your 03 is the best shot and changing fluids, the other two I would keep using Dex3 to be safe
