Sluggish and no reverse!

Driving my diesel the other day. The vehicle feels slow and sluggish, almost as if 1/2 the power is gone. Then trying to parallel park, shift in reverse, nothing...feels like it's in neutral. Park it somewhere, shut it down. Wait a few minutes and everything is fine again. Any idea what's going on. I've search the forum...from limp mode to shifter problems. Just wanted to ask before heading out to the dealer.

Sounds like an ignition related issue. However, I know next to nothing about diesel ignition systems.

Just a follow-up. replaced the speed sensor unit in the transmission. it's called the ElectroHydraulic Control Unit (be careful, there's a different unit for '07 and '08). It's hidden above the pan so did the tranny fluid (90000kms) gasket and filter as well. The transmission shift very nice now and with the new fluid really helps too.
