just bought a honda 2009 crv, the trans fluid was low when i checked, i added dw1. it was driving fine then it started slipping again, i poured the entire liter after i felt it shifting harder. after i added half the liter it began shifting harder after 2 days, should i drain the trans fluid and add more dw1?
You have a leak somewhere; you better get on that pretty quickly or you'll overheat and trash the transmission. Automatics are driven partly by hydraulic pressure, and it is very sensitive to fluid pressure -my 1979 Pontiac has a 2-gallon capacity and I notice it starts to delay shifting when only a pint of fluid is missing. One pint equals a half quart. It has a very slow leak. Take UV dye that's compatible with transmission fluid, get a pair of funky sunglasses that come in a kit and look under the car for leaks.
