Contour Enthusiasts Group Archives Forums General Troubleshooting ATX slams into 2nd from 1st, should I be worried?

'99 2.0L Contour with 40k miles. If when the car is accelerating in 1st gear and I suddenly take my foot off the gas (as would be the case when going a short distance between stops) the tansmission will noticably "bang, slam, etc" into 2nd. The car has done this since I bought it used at 32K. Most of the time I can avoid this by acelerating more slowly or by letting the car go into second before taking my foot off the gas. A drain and refill (2x) of the ATF did not make a difference. I also noticed this same behavior in another '99 2.0L Countour I test drove before buying this one.

Is the CD4E just not a smooth shifter or should I be worried about this? Thanks!

Just don't take your foot of the gas. It's normal for our cars. A chip and/or performance transmission kit would probably fix it. Though some cases get worse than others and require attention. I'm sure your car is fine though.

Redcon- Thanks for the reply. When you say a chip do you any of the performance chips or is there one that specifically addresses this program? From what I'm gathering this behavior is not a mechnaical problem but the PCM "telling the transmission to slam into second" under certain conditions.

I also found this thread:

Some claim resetting the PCM can help. I might give that a try today

My V6 SE ATX did this too. Just don't abruptly take your foot off the gas.
