I have an automatic 4 cylinder 2000 dodge neon with what I believe is a transmission problem but I have no idea how to fix it. The car will start up just fine and I can go in reverse without any problems. But if I accelerate start from a stop to quickly my car will shake pretty heavily. Then when I reach about 20mph (while the transmission goes from gear 1 to 2) my car will shake even harder if I am accelerating too fast. I talked to local mechanics and I have done what they said but I still have yet to fix it.
So far I have (in chronological order):
replaced the air filter
used an injector cleaner (which caused sparkplug problems)
changed the motor mounts
added lucas transmission fix
lubricated the transmission line
*also when I put the transmision fix fluid I noticed that the transmission fluid level was too high, I wasn't able to drain and fluid out so I only put in about 6 oz. Of the transmission fix. Could have too much transmission fluid cause the violent shaking.
Thank you in advance
