XADO 1 Stage Manual Transmission Additive Revitalizant - Transmission Fluid Additive - Friction Modifier and Conditioner for Instant Shudder Fix, Stop Slip Transmission Treatment (Blister 27 ml)

I was scared hearing a whizzing sound and the engine light came on while driving immediately application. Eager to see the effects I did not read the instructions. However, after allowing the engine to run as stated on the package, the whizzing noise stopped, the engine light went out, acceleration was smooth and the best part is I get more mileage per gallon of gas. I rated the product as supreme.

I should never have done this as a preventative on my 2012 Rav4 that was running perfectly. I added the tube to my transmission and then drove it around and it started slipping. then hard slipping. I took it to the auto place to have all the transmission fluid removed and it is still doing it. they did a diagonisics on it and it came back "P0776 pressure control solenoid "B" Performance or Stuck off" this is an issue with the Solenoid now .I have a check engine lite on and LSD red light flashing on dash. Now I have to take it to my Toyota dealership tomorrow and get that fix. Could cost me $500. I will update tomorrow.

put this in my rangers rearend and quieted down alot . only driven it 27 miles so far

This additive was for you 2012 Toyota Rav4 , which only come in 4 or 5 speed automatic transmission, the reason your transmission started slipping is that you added Xado manual transmission additive, not the one for automatic transmission, not Xado fault for your negligence, to anyone reading this, I been buying Xado for over 10 years before they had U.S. distributors, never had a problem with it.
