So after logging in a few weeks of conversation here on the board, I was beginning to feel pretty auto savvy. Savvy enough to think i could change my own spark plugs. Any of you who remember my first few board questions know that this was a huge step for me. So after i change them, Im crusing along pretty well for my first two or three drives (and swelling with pride). Only now when i drive the car i get a hard lunge and disturbing thud, at roughly 20mph. After that i am smooth sailing into about 80mph. After getting this i now baby it through the 20-30 mph range. It still drops very hard. But yesterday I sped into it to avoid being hit by another car. The transition was very smooth, or pre-plug change normal so for the remainder of my trip I would accelerate through that range. have i changed my plugs incorrecty or is this possibly the result of some other ailment? thanks

Ricky,

Now it may be time to tackly flushing the transmission fluid. Sounds like the tranny is acting up a bit.
