Auto-Rx Customers Questions & Answers

Frank · Frank

Hi, your product sounds very fascinating but in spite of your very informative site I have a question. Would it be harmful to add Auto-Rx to the transmission of my 1993 Ford Taurus with about 125k miles on it and not change the transmission oil? I'm pretty sure it has never been changed and am leery of do...

Hello, My transmission, a 4T60 in a 1989 Grand Prix, has a known defect caused by a shrinking and hardening inner clutch seal. The symptom of the problem is that the transmission will not engage into drive until the transmission fluid has warmed up. The warm fluid makes the seal expand to contain the fl...

In a few forums the general opinion is that transmission additives SHOULD NOT be used in a Honda. My 99 Accord (auto, 4 cyl) slips going into 3rd and 4th and has a small seal leak. Found some metal filings on the drain plug magnet at the last fluid change. Comments on experience with transmission addit...

Chris, Let me give you my limits of knowledge on the topic. If this is the Honda 5 speed (which I think it is), Honda retrofitted an oil jet for a design defect. This solved that evolution of issues. The next to appear was pressure switch failure. Most issues encountered by the post oil jet refit or OE...

Hi all, I have a 99 corolla, 105000 miles. There has not been much discussion which ATF to use with auto-rx. I currently have Valvoline max life (High Mileage) in my transmission. I put it in this summer (~1000 miles ago) and also changed the filter. The transmission is running fine and I would like it to...

I have a 1988 Suzuki Samurai. The manual transmission shifts up fine, and downshifts into 3rd and 4th fine. When in forward motion, it is difficult to downshift into second, and impossible to downshift into 1st without double-clutching. It does not grind, and I can hear the transmission spin up...

My '94 Ford F150 w/E4OD auto transmission is well overdue for a transmission fluid and filter change.

While greasing the driveshaft on my 2000 Tundra, I noticed a seal leak on my tranfer case.

Hello I've been having problems with my intrepid as of late and wanted to know could it be because I left the auto rx fluid in my transmission for too long?

I recently purchased a 2006 Ford Expedition with 41K on the odometer.

My transfer case on my 02 F-150 FX4 is coming due for a fluid change soon. Should I add some(how much?) AutoRx in and run it 2-3000 miles then change it? I am going to switch to Amsoil synthetic AT fluid after I drain it.

I have been told that after my 3000 mile ARX cleaning I should bring my car to a T-Tech location for the ATF change. And they do NOT need to replace the filter? Is this the correct procedure? Thanks.

Hi, I bought some Auto-RX for my Caddy Northstar, but i am afraid to do the transmission treatment when the trans is shifting perfectly fine. Is there ANY chance auto-rx could shake something loose?

Frank, Almost as soon as I put in the Auto-Trans cleaning dose I started to feel a change in the way my Transmission shifted and functioned. At 900 miles it was working like new and at that point I flushed out the old fluid and put in the new fluid. Thanks Jeff Short
