I've used Auto rx in both engines and transmissions for several years and recently put some in daughter's 2001 Volvo V70 T5 (AT) which has occasionally been slipping when changing gears. She contacted Volvo dealer who told her it shouldn't have been put in, and that these transmissions use a speci...

The car is a 1993 Audi 100 CS quattro with a ZF automatic transmission. The odometer showed 227000; past maintenance history not known. The engine would rev a few hundred rpm on the 3-4 upshift when at operating temperature. I changed fluid and filter; it did not help. I installed Lucas transmissio...

My old Toro rider has a Hydro-gear transmission. It is a sealed unit, filled for life, a notion that I strongly oppose. I intalled a used one at 540 hours because the original failed catastrophically. I think it failed because the oil was never changed (it was very black). Now at 1070 hours I removed the...

Would Auto-RX possibly help this problem? (I also noticed that I've over-filled the transmission fluid by quite a bit. Could this be the problem?)

Transmission Repairs. Replacement of the torque convertor can be something that we could prevent. As we know folks use auto-rx after the fact in most cases. That is to correct an ill transmission. Very few folks service their transmissions at the appropriate time based on the fluid life. Many can...

I haven't worked on cars much, so my question might be pretty dumb, but in my manual transmission car, where would I add the ARX for a transmission treatment--since there is no ATF fluid? Thanks much. ML

I just added auto rx to my transmission in my 1994 Subaru Legacy with 160k.

A friend of mines hondas transmission has been bucking. She ran out to the local trans. service place and got a 3K estimate. I asked her to try ARX before she plunked down 3K. She agreed and I poured the whole bottle into her AT. Did I screw up? -- Edited by Frank on Saturday 25th of May 2019 12:47:33 PM
