There is a post on BITOG about a guy who has a Lincoln Continental which is a Ford product, he took his vehicle to a Nissan Dealership to get a T-Tech done and is having problems with his transmission shifting, (He cannot get above 20 m.p.h.) What can we learn from this, if you go to get a T-Tech done after using 6 ounces of Auto-Rx ask if they will drop the pan and change the transmission filter, if they will not, go somewhere else that will. Another problem is that wherever you go to get a T-Tech done you have no idea what vehicle was in there before and what kind of fliud was used, you have no idea what kind of fluid was in there from the last T-Tech procedure, Ford transmissions are finicky and there is no way you can mix Nissan trans fluid with Mercon V. The other concern is the trans filter, no T-Tech procedure is going to clean this out, it must be changed after an Auto-Rx cleaning, no if and's or buts. Now there is something you can do when going for a T-Tech, bring a few more quarts of fluid to have the technician flush out what was in there before. I still think the best thing is to do the T-Tech yourself, it is easy to do. A T-Tech procedure mixes new fluid with old fluid so you are really not getting all of the old fluid out. I found a Tranny Calculator on BITOG and through 7 drain and fills I went through about 40 quarts of trans fluid. $2.50X 40 quarts equals $100.00, about the price of a T-Tech and they do not use 40 quarts of trans fluid. The only way to get out all of the old fluid is to go someplace where they have a Pump inlet machine. Here is how it works, a technician drops the pan and sticks the hose from the machine directly into where your trans filter is and everything in the trans, valvebody and torque converter are flushed out, they need 20 quarts of fluid for this procedure, almost twice the amount of fluid that is used in a T-Tech procedure. Like I said, do it yourself for piece of mind but if you get a T-Tech done and have problems you have been warned and it is not the fault of Auto-Rx.
Taking a Ford to a Nissan dealership perplexes me, anyway. I took my Grand Marquis to the Lincoln/Mercury dealership for the T-Tech, and everything seems great. I still want to drop the pan and change the filter myself in the next 10,000 miles or so, however.

He posted back too me and said a little bit of Nissan trans fluid should not have hurt his transmission, my 2004 Mercury Marauder calls for Mercon V, I read the owner's manual and it did not say well if you take your car to a Nissan Dealership it is not a problem mixing in some Nissan transmission fluid. Taking a Ford product too a Nissan Dealership is absolutely mind boggling too me.
Any amount of transmission fluid not specked for the transmission will create shifting problems. T-Tec is a machine that for $99.00 cleans out old fluid (including whats in torque converter-filter)) while filling unit with new transmission fluid that is correct for your transmission.
This transmission post on bitog is the result of a botched Transmission Service. All that needs to be done is go some where that offers T-Tec Service (not a new or used car dealer or a friend etc,etc)) and clean it properly.
This person has used Auto-Rx in his engine without any problems (he did application himself) think it is important to remeber Auto-Rx works if you work it.
A T-Tech competently used where they drop the pan, blow the cooler drain line, and replace the filter will clean out a high percentage of the old fluid. Allowing the torque converter to mix is a necessary evil but a fast lube T-Tech that also allows the sump to mix pretty much accomplishes nothing no matter how many quarts go through.
The Benefits of ATF Exchange are clear with T-Tech FAST
T-Tech features quick connect hoses and an easy hook-up to the transmission cooling line for a quick start. From hood-up to hood-down, most vehicles can be serviced in 15 minutes or less. ASSURED
Because the exclusive T-Tech process is powered by the vehicles own pump, the dangers of over or under-pressuring the system are eliminated. Plus, the T-Tech exchange is 100% proportional - for every quart removed, a new quart automatically takes its place - to ensure an accurate fill every time. SMART AND CONVENIENT
An auto-alignment feature means there is no need to verify fluid flow prior to starting and no possibility of a reverse connection. An auto-bypass safety switch frees the operator for other tasks by sending the unit into bypass mode upon completion of the service. A drain pan feature provides convenient draining of the transmission pan prior to removal or other applications. COMPLETE
The exclusive T-Tech process exchanges virtually 100% of the vehicle's ATF in a proportional, even exchange. Old transmission fluid is pulled from the most stubborn and difficult-to-reach areas of the transmission system, including the torque converter and cooler.
Jared, I am glad you asked this question, and the answer is NO, I will tell you why. The 1st time I dropped the pan there was nothing in the trans filter, my trans filter is a screen, Auto-Rx did such a good job liquifying everything that everything went through the trans filter. I would not recommend this with a felt type filter. I would recommend that everyone have a strong magnet in the bottom of there trans pan to catch anything missed by the trans filter. Basically I just drained the trans fluid each time. I did Google Transmission Flushing Machines and read that with a T-Tech half of the fluid in the pan goes to the converter and the other half goes to the cooler lines so that with a T-Tech you are not flushing all of the old fluid out, this is what I read and I will have to investigate this more.
