Question Trans drops in to neutral at high rpms

Hi my 05 wk has a mind of her own... When at highway speeds or high rpm(using the paddle shifter)the RPM drop to idle 900-1k then the trans is in like a free fall until u hit the gas get the RPM up to 4-5k then the trans clunks back in to drive. I have talked to a lot of plp and the only thing the can think of is the paddle shifter is bad or I need to reprogram the computer. I don't have sufficient funds to bring it in to the dealer or buy a new paddle shifter module ANY thoughts or the same problem out there I need some help. Thanks

Re: Trans drops in to neutral at high rpms

I wasn't aware the th '05 WK had a paddle shifting option (unless you added them as a mod). If however, you're talking about the center console shifter (which I call a slap-shifter), then I would lean to a PCM/TCM problem.

Sounds like your low on trans fluid... Any leaks?
