So my crv has what appears to be a transmission issue. It has a clunking hard downshift into first when stopping but only after the car has been driven for a while. It seems to be related to temperature because it didn't do it in the winter. Have already changed the fluid, drove then changed again (did this three times to approximate a flush) and have put an additive in which hasn't seemed to have any effect. It's been doing this since I bought the car last summer and hasn't seemed to get worse but it's tough to say for sure. The other thing I've noticed is that if I try to slam on the gas from a stop it makes a kind of growling sound and there's vibration from under the car. When this is happening its not taking off like i would expect. Has never had the check engine light pop up. I had it seen by a mechanic I think 5 separate times before it was even diagnosed as a transmission issue. The response I kept getting was the differential mount and bushings so I had those replaced which had zero effect. At this point I'm planning to take it to a transmission specialist but I was thinking maybe someone had some thoughts/experience to direct the inspection. After having my car looked at so many times with no answers my faith that this time will be it is pretty low.
