Dexron VI is good stuff

[tractorman]

For the benefit of mankind (especially those with GM products), I'm posting my review of Dexron VI. I changed the tranny fluid in both of my cars recently- an '01 Lumina with a 4T65e, and a '94 Corsica with a 4T60e. Both transmissions have been serviced very regularly (every 15,000 miles) for many years. Both vehicles have over 150,000 miles on them.

After the fluid change, the 01 Lumina drives exactly the same as before. The transmission has always worked fine, and the Dexron VI made no apparent difference. But- the '94 Corsica's 4T60E hasn't been completely flawless for years. For the past 30,000 miles or so... when I would take off quickly (half throttle or more), the transmission made sortof a periodic vibration ( a quick rrrr-rrrr-rrrr) just before shifting into second. It never really got any worse and I wasn't too concerned about it. After changing to Dexron VI, the noise just went away. I thought it was my imagination at first... but it's been two weeks now, and I can't even MAKE the car make that noise anymore. In my humble and unscientific opinion... Dexron VI is good stuff (and it better be at $6 a quart).

My only question is: They still made the Lumina in '01?

that is what I said. Good to hear about the noise.

Yep, they sure did. It was identical to the 2000 Lumina- put together from "remaining stock" and sold exclusively to fleets. I bought it from a fleet auction down at the local college.

About the noise- I recall that somebody here described that exact noise in their own 4T60E some months back. I don't remember who it was. I told them not to worry about it as my Corsica has done that for years... but now there's an easy fix.

Thanks for the review I might try it out on the next trans service I do.

I'm wondering, does Jeff approve Dextron VI for use with his EP LSD's??

Or is it too slick... I know I tried B&M trick shift synthetic and that just make the diff slip... Maybe I'll shoot him an e-mail

Yeah I have been using it for quite a while now at work including in a few rebuilds. The Dexron VI superscedes Dexron III and that part number for the III is no longer available, basically whatever is left at the dealers, etc. So after it is all gone, thats it.

as ive stated before, petro canada as well as other oil manufacturors are going to be producing universal atf, wich is just dexron 3 under a different name
