Thanks guys,
I used Dex III here in Hawaii and in Seattle.
I checked and checked and checked the fluid level.
It was hot to the touch and I was worried about getting burned the last time.
I pulled the plug, jumped in the rig and ran it thru all the gears several times while parked. I pumped it so full it was pouring out, prob the whole last quart I put in came back out and it was way more than warm fluid running down my arm while I replaced the bolt.
But yeah the reverse is slow to engage, it has been as long as Ive owned the rig so it makes me think its been on its way out for a while. I have always had to wait to make sure before applying any gas for reverse but in drive it jumps right into gear and is tugging on the brakes.
