Hello,
2009 Wrangler Sahara Unlimited. 192k Automatic transmission. 130k
Been having issues with it hard shifting in and out of 2nd gear.
It only does this about the first two times after starting up and driving the vehicle. If I drive the jeep all day and do not shut it off the problem does not persist, but the monent I shut the jeep off, start it up again, and then begin to drive it hard shifts again about 2 times and then never does it again, until I start this process all over again.
Not sure if this has something to do with it but... There is also a WaWaWa sound coming from transmission or somewhere very close. It's tempo is congruent with the rpms and not the speed of the vehicle(it's not the tires or bearings) This WaWaWa is not always there but is there more often than not. Just odd that it comes and goes.
The shift from 1st into 2nd is quite harsh - a few times it's chirped the tires. The shift from 2nd into 3rd is much more mild, but is still hard enough that it raises some concern.
After the first two initial hard shifts are played out, as stated in the first paragraph, the transmission shifts smooth as can be for the remainder of the drive.
There is no whining when shifting.
I have replaced the PCM(partly because I was having other issues that are now fixed)
Replaced the transmission a couple of months ago(it was used and had 120k on it) the oil had been completely drained and filter changed out before the install.
Several sensors like MAP, MAF, O2 etc... have been replaced as well.
Any information or wisdom on what this could be or IS will be GREATLY appreciated!
