A very odd a peculiar thing I got going on.

Alrighty fellas. So my transmission is full on fluid [I have not topped it off, full of what was already in it] and I have come to notice something. When I crank my truck up in the morning it cranks fine, idles fine. The first gear I shift to to leave out of the driveway every morning is Reverse. Then afterwards I go into drive, drive to work. Truck shifts fine. No jolts, jerks or delayed shifting. But here's my peculiar delimma. So when I get to work and park, my rpms go up. Also my Reverse THEN jerks when I shift to back in. It doesn't do it cold or if I let it set for a few minutes. But the second I shift to drive to Reverse it jerks/jolts. I do have 3 videos. The 6 second one is initially starting up. The 25 second one is when I park and you are able to hear the rpm difference from the initial start up. The 30 second video is me changing gears demonstrating the odd delimma. Reverse you can clearly hear the sound and me jerk with it a bit

And here is the idle when I took it down the side road and parked it. This is what it sounds like every time I turn it off. I'm kinda at a loss here. Everything shifts good but Reverse is the only one that jerks when I drive it for any amount of time

the CC doesn't really host videos very well.   you'll want to upload to youtube and then share.

Yeah. I considered that. I'm also just considering biting the bullet and doing a whole transmission fluid change....although some part of me keeps telling me the fluid isn't necessarily the answer. Because it's only reverse I'm having- I won't say difficulty with, but the only one that jolts when I reverse after driving.

When was the fluid last changed? If you don't know, do a drain and fill. 

Requires a gallon of Dex/MercIII fluid available at Wally World.
