First of all, the gears are very slow to engage, most noticably in cold weather. The last couple days, my gf (it's her car) says that it just stops pulling all of a sudden. I went out today and started the car, put it into reverse and then drive, watching the rpm, and waiting to feel it pull takes at least 4 or 5 seconds before it'll go.

Also, the speedo is noticeably off. It is very slow to come up, and sometimes has an epileptic bounce to it.

What gives? Anyone got the answers or at least some ideas?

Thanks all in advance!
