There have been three TSBs issued regarding ATF+3 and ATF+4 usage in 1999 and earlier 41TE/AE transmissions.
 
TSBs 21-006-01 (June 2001) and 21-004-04 (March 2004) specifically say NOT to use ATF+4 in 1999 and earlier MiniVan transmissions. One of them (I forget which) states that the reason for the restriction is that the torque converter lock up feature might have a problem with the ATF+4. I read elsewhere (allpar.com IIRC) the same as you that the ATF+4 could present a problem with the seals.
 
Then, not even a year ago, Chrysler released TSB 21-010-06 (April 2006) that inexplicable reverses the two previous TSBs with no explanation as to the reasons for the apparent contradiction.
 
Personally I still suspect that the introduction of ATF+4 into my 1998 DGC with just over 90,000 miles on the clock was a contributing factor to my transmission failure. I have been soundly criticized from many fronts for stating that opinion, however, that continues to be my opinion none-the-less. In my case the good news is that my Factory Remanufactured transmission is specifically designed for AFT+4, so I no longer have to worry about the lack of ATF+3 availability.

Many thanks, Shipo, for the reply.
 
This morning I took our '96 LXI to the independent transmission shop that has serviced the transmissions in all of our cars (mine, wife's and all of my sons') and once again allowed him to change out the fluid with the universal fluid containing ATF+3 additive that he used 3 years and 30,000 miles ago. Did not use ATF+4. The magnet in the pan was clean of any debris. He also inspected the small leak and said it was a common problem with the crimp that connects the steel line to the rubber line on the transmission cooler (for the towing package). A new line is $65 plus installation, but he acknowledged that it probably would not cause a catastrophic failure, and that as long as I continue checking the tranny fluid it should be fine. The vehicle only has 92,600 miles, so I'm hoping to get about 3 more years of service out of her.
 
He said it would not be a problem topping off with ATF+4. I still have 1/4 quart of ATF+3 left in my garage.

If ATF+3 is no longer available, ATF+4 is a MUCH BETTER alternative than a "one size fits all" fluid with an additive to make it "just like" ATF+3. I can't believe with all the available information out there, shops that "specialize in transmissions" still don't get it! It should be illegal to introduce any fluid into a Chrysler 4 speed electronic transmission, that is not a certified DC licensed fluid.

"If ATF+3 is no longer available, ATF+4 is a MUCH BETTER alternative than a "one size fits all" fluid with an additive to make it "just like" ATF+3."
 
I have to agree. In spite of the fact that I think that ATF+4 isn't the best fluid for a pre-2000 minivan transmission, I'd still rather use it than a Pep-Boyz mystery mix.
 
Were it that I still had a transmission that speced ATF+3, this is what I would be using:

Any opinions on replacing an overdrive tranny with a three speed? by toasted_tranny

Hey folks.
 
The overdrive transmission in my V-6 91 Plymouth Voyager is almost completely gone. We dropped by a wreckers and they have suggested we could replace the the my toasted tranny with a three speed transmission.
 
Any body want to tell me some pros or cons of this idea?

Pros: 3 speed is less complex more reliable.
Cons: No overdrive, less MPG, may not match up to existing transmission wiring/computer harness, may not be able to achieve electronically controlled torque converter lock-up in 3rd gear, may not match up to bell housing etc. etc....

Yes, the Havoline ATF+3 is a DC licensed product. Problem is, where do you find it, and how much longer will it be available? As soon as DC discontinued ATF+3, it seems like everyone else who was licenced to produce it, shifted to ATF+4 production during the last two years when DC dropped exclusive rights to it.

I have an 02 t&c that clunked in low gears. I thought my dealer was crappy. Sounds like you got stuck bad. I have the extended warranty and the whole transmission was rebuilt for the $100. I don't seem to have the same issues with the transmission. I have 93k on my van. I hope to get it to 150 before having to replace the engine.
 
overall i like my van- just always pay the 1600 for the extended warranty and then make a nitpick list and bring the vehicle in because you only pay the money per visit not per item on the list.

Towing Question by salaryman

I just bought an 2003 Dodge Grand Caravan ES and it does not appear to have the towing package.
 
What can I tow and what upgrades would permit me to tow what?
 
Obviously, a tranny cooler would be the first thing to do...
 
What else?
 
Thanks

Another Tranny Problem... by linkc

At around 95,000 miles of flawless service, my '02 T/C transmission started making noise and shifting hard, so I had the fluid and filter changed. It stopped for a while, but soon the noise came back.
 
I thought enough was enough and traded it yesterday for an '05 with 18k miles. Mine was at 107,500.
 
I sure hope this newer one lasts a while...
