I have a 2005 Jeep Liberty 2.8 CRD which uses ATF+4 in its RFE545 transmission. Can I use this in my transmission?

I would ask a local transmission shop. I have used this in my Contour, CRV and Civic. It seems that a lot of transmission shops use this on rebuilts to avoid failures under warranty. I didn't over think it with my Honda vehicles since such a small amount is added to the transmission. I would not only check with some transmission shops, I would also check some of the blogs that are relative to your vehicle.

Which lubegard to use? red, black, universal....etc this is for 2007 toyota corolla lock-up solenoid issue.

It is compatible, will it help ? Its worth a try. I would do a couple of poor mans flushes first, drain the pan & refill with fresh fluid, drive 200-500 miles & repeat until the fluid comes out looking nice & red, then refill & use the lubeguard, good luck!

Can I use this on my 2007 Toyota Rav4 v6 ?

Keep in mind that some people do not like any form of a liquid mechanic. This product is proven to help clear buildup on shift solenoids plus other slippery benefits, but it is definitely not a cure for a bad transmission or a band aid to avoid replacing dirty old partially burned oil. If your automatic transmission is still in reasonable working condition, but is a bit sluggish when changing gears, mildly slips out of gear on occasion, or vibrates ever so slightly when negotiating a slight incline at a slow speed while in a higher gear (i.e., low rpm), this product - like other similar products - will typically improve old car transmission performance and decrease some of the bad "vibrations". A neglected transmission that is still in good operating order may benefit from two or three properly sequenced transmission fluid flushes - each time supplemented with a dose of this or similar product. Always defer to your favorite mechanic - not to one of the national chain lube shops that offer "rapid" service. Also check the maintenance section of your car's manual. My car for example recommends changing (flushing) the transmission fluid at 150000 miles, but does not mention a need to change the transmission oil filter. - So, first read the manual to gain some important insight.
