Chrysler Repair: Power Flush Chrysler A604/41TE Transmission, chrysler grand voyager, chrysler a604


Question
QUESTION: Roland,
How do I power flush this transmission? It's in a 2000 Chrysler Grand Voyager. Is there a way for me to do it, or should this only be done at a shop?
Thanks,
Mike

ANSWER: Hi Mike,
I only know that the power flush involves a pump and collection system to move the transmission fluid not only from the sump of the transmission but also through the torque converter and the cooler and hoses that connect it the transmission. I have not heard of a do-it-yourself procedure on this job. I don't believe that it is that labor intensive that you would be saving a significant labor charge but do some comparison shopping and also take into consideration the cost of about 10+ qts of ATF +4 fluid in the cost estimate. I don't believe there is anything high tech about it but you still need the pump and associated tubing and the experience to do it properly.
The tool is described in the manual as a 6906A, probably manufactured by the Miller Tool Co., and there is a page in the manual that describes the procedure. Sovents are also involved in the process. Should you acquire the tool let me know and I'll send you the page of instructions mail, after making a xerox copy.

QUESTION: Roland,
I will probably have this done by others. What is your opinion on Valvoline Max-Life(R) ATF+4 with stop leak? Is that a good idea to put in my transmission with just over 100,000 miles on it? It does leak a little...
Thanks,
Mike

Answer
Hi Mike,
Sorry to say I haven't compared the choices for ATF+4. I can't be sure whether there is any down side to the 'stop leak' additive.
Given the cost of rebuild I would be a little reluctant to put additives along with the ATF itself. But if the leak is costly, then try it.
