It's the service that is designed to replace virtually all of the old, degraded transmission fluid with fresh fluid to help prolong the life of your transmission. Common Reasons For Transmission ProblemsĪAMCO's exclusive Power Purge® and Power Purge® Plus Transmission Flush (Fluid Exchange) services are the most comprehensive transmission maintenance services available anywhere.Ended up replacing 16 quarts this way, then added all the different "fixes in a bottle." So far, the "unholy mixture" is doing well. The way I changed the fluid was to pump fluid out via the filler tube with a little hand pump, (it works great, you can get them at Lowes for about 12 dollars), then replaced said fluid and drove around for a while, then pump more out and replace, drive, pump more out and replace, then drive. Two months later, Taurus is still shifting very well with no slips, bumps or jerks. While there were some who strongly warned me not to use "snake oils," there were others who advised me I needed to clean the varnish so the innards would work properly. I was told by wise people here on Bitog that probably, my tranny was suffering from varnish inside the innards of the tranny. Shifts great and no more slipping or jumping into gear. Finally, I added a bottle of "Seafoam Trans Tune" and literally, within two miles, transmission was working perfectly. When I added a bottle of Lubegard red, there was a slight change, but not enough to make me happy. I added a bottle of Lubegard silver, no change. I added two bottles of the "Lucas" tranny fix in a bottle, (it's really thick stuff). I changed the fluid with Advanced Auto Dex/M and the filter as well. For many months, it had been slipping in first gear and "hesitating" between 3rd adn 4th, (like you said, it was "thinking" about shifting). I've got a 1993 Ford Taurus with the AXOD metric transmission.

If I were you, I'd use the Maxlife or a Dex VI. Any name brand Dex/Merc would be acceptable as well although they are no longer licensed so what you are getting will vary some, but they generally are good fluids.ĭo a pan drop and filter change, put the shift kit in while the pan is dropped and fill it back up with whatever fluid you want.

Many people use Maxlife Dex/Merc which is full synthetic and are very happy with it. The D4 was an experiment for fun as much as anything.Ī pan drop and filter change will get out 7.5-8 quarts, a large % of the fluid. I probably would just have stuck with the Dex VI if I had it to do over again. I have Redline D4 in it now which is working good it seems. I do a pan drop and filter change every 30k miles. I had a great UOA of my trans oil using Valvoline Dex VI from 90k-180k when I tested it at 180k. It will occasionally shift more firmly when hot but it never slams like it did. I put my kit in at 120k miles on the odometer and I just hit 200k miles last week, still shifting good.

You can hear the pump whining as well when this happens. If the computer detects the shifts as being too slow it will think it is failing and go into a fail safe mode and cause the pump to go to max pressure and cause the shifts to slam from gear to gear.


It keeps the shifts within specification. I had a hard shifting problem with my Grand Prix and it was fixed by a shift kit similar to the Trans Go kit mentioned. I agree with the other poster that suggested the shift kit. I might mention sometimes when putting it in gear it is kinda loud its hard to describe the sound Oops!! 2003 century, it's a slight slam, it seems like it thinks for a second then shifts there is a noticeable buck on All upshifts. When you say, starts to shift hard, how hard? Slamming into gear like it wants to self destruct or just firmer than you want?
