Iso: a reputable mechanic to diagnose and repair or refer me to a garage for an 03 buick rendezvous. It's started making a rattle sound when I accelerate only when I accelerate, and it's leaking transmission fluid from somewhere. It leaked a while back and it was coming out of the dipstick tube so I had the seal replaced on the dipstick and it fixed it. I don't have tons of money so I'm looking for fair prices and not someone to jerk me around trying to buy this and that. I talked with someone before but I've lost his number. TIA
