In 1995 with the New Dexron 3 and the advent of the 4T40-E ( Replaced the 3T40 ) The 4T40-E supposedly had updated side pan and bottom pan gaskets which were said to remian leak free for life, as well as fluid that should last the life of the car( Dex 3 )... The fluid replaced Dex 2 and Dex 2E, Supposedly it just had a better additive package that was not supposed to wear out so quickly... Life long fluid... Yeah right!!... Makes me think that the 4T40-E was used on the throwaway cars( I don't mean that in a bad way at all )...
But it was funny that all 4T60-E'* and later 4T65-E'* had the dipstick from the factory... I do wonder if overheating played a factor in this?
In the 95 Owners manual it states Dex 3, change at 50,000 if the car is Fleet, Taxi.... Bla Bla Bla Severe Duty... If not then change the fluid and filter at 100,000 miles... Notice that the gaskets for the 4T60-E were quite good as well...
Even if I had a GM car with no dipstick it would still get the fluid and filter change as often as my 4T60 and 4T60-E no matter what...
Is there any good info on the Dexron 4 fluid yet? Or better yet what was improved in the additive package?

The gasket point you bring up is a good one. From early 90'* I thought the gaskets were designed to be reused as long as there were no obvious issues with them.
I wouldn't consider it a "lifetime" gasket though..lol

They are designed for reuse as long as they are ok, and are not broken or damaged anywhere... If they are nicked or damaged then it should be replaced...

It is a metal gasket with the rubber seal inlaid. Very nice gasket..

GM Introduces New Automatic Transmission Fluid For 2006 Cars and Trucks
* New factory-fill fluid standard in all 2006 MY Hydra-Matic transmissions
* Significantly improved viscosity, shift performance and fluid durability
* Available through GM Vehicle Care products as DEXRONŽ-VI
* Approved for service application on all prior model year Hydra-Matic automatic transmissions
Pontiac, Mich. - GM, in conjunction with Petro-Canada and Afton Chemical Corporation, have developed a new, improved automatic transmission fluid for all 2006 model year Hydra-Matic automatic transmissions. Developed for factory-fill as RDL-3434 and registered for service fill as DEXRONŽ-VI, the new fluid represents a significant improvement in automatic transmission fluids and is the direct result of GM'* industry leadership in the development and production of automatic transmissions.
"For 65 years, GM has led in the design, development and production of automatic transmissions," says Tom Stephens, group vice president for GM Powertrain. "This knowledge and experience has helped us work directly with the petroleum industry to develop a new fluid that will further accentuate the performance and reliability of GM'* Hydra-Matic transmissions."
Automatic transmission fluid (ATF) is considered the life-blood of the automatic transmission. It is used to transfer power in the torque converter and provide the pressure to apply the transmission'* various clutches and bands. It also is used to clean, lubricate and cool the components of the transmission. GM'* new transmission fluid, DEXRONŽ-VI, was developed to have a more consistent viscosity profile; a more consistent shift performance in extreme conditions; and less degradation over time.
Beginning with the design and development of GM'* new Hydra-Matic 6-speed rear-wheel-drive transmissions, GM Powertrain engineers determined the need for a new transmission fluid to withstand the complexity of the clutch-to-clutch transmission operation. Additionally, GM engineers identified opportunities to improve viscosity, durability, and impact on fuel economy with a new fluid.
"The development of DEXRONŽ-VI is the first time an automotive company has worked so closely with petroleum and additive companies to develop a new fluid," says Roy Fewkes, driveline fluids group leader, GM Powertrain. "The result is a new fluid that significantly outperforms existing fluids in every aspect. In fact, we have had to significantly extend the length of our durability tests to fully test the fluid'* capability."
Internal GM tests have demonstrated DEXRONŽ-VI to deliver more than twice the durability and stability in friction tests compared to existing fluids. It also has demonstrated superior performance in pitting, foaming, oxidation and shear stability tests.
GM will begin factory-fill of the new transmission fluid on April 4, starting with the new Hydra-Matic 6L80, produced at the Willow Run transmission facility in Ypsilanti, Mich.
DEXRONŽ-VI will be available through genuine GM Vehicle Care products at GM authorized dealerships and service centers in Summer 2005.
General Motors Corp. (NYSE: GM), the world'* largest automaker, has been the global industry sales leader since 1931. Founded in 1908, GM today employs about 324,000 people around the world. It has manufacturing operations in 32 countries and its vehicles are sold in 200 countries. In 2004, GM sold nearly 9 million cars and trucks globally, up 4 percent and the second-highest total in the company'* history. GM'* global headquarters are at the GM Renaissance Center in Detroit.

I really do wonder how much better this stuff really will be, and I wonder how rediculously overpriced it is. I am thinking about putting some in my 4t60 to try to help extend the life of it (not that this fluid will really do that) but I'm sure if I go to get some it will be like $10 a quart.
It will be interesting to see if this stuff actually makes it big or not. Sealed transmissions sound like the stupidest idea I've ever heard of too.
