[QUOTE="kleake, post: 1389518, member: 25987"] Update: Last night it was late, I was setting in gravel so couldn't get a full throttle test. Today, I was on pavement, had to put it in 4x4 to keep from turning the tires, and I still couldn't hold it to a stop with just brakes. I will say though, the reverse pressure is MUCH better than it was last night, but it would still slip under very heavy throttle. I do have a tuner, but I had it turned down, but it's still pushing a lot of power at that point. Last night there was little to no variation between reverse and any other gears, however, today there is a 50-60psi increase in reverse. Engine was at 195 today, probably 175 last night. P=80psi R=140 Stalled up max 200-250 at 80-90% throttle, but jumpy so hard to tell exactly. RPM was holding at 1500-1800 until 65-75% throttle, then it started to slip and went to 2500 before I backed off. Maybe .5-1 second is all I gave it once it started slipping. It was at about 200psi when it started to slip. N=80 D=80 Stalled up max 250ish. I only got to about 80% throttle and I couldn't hold it back. 3=80 Stalled up max 275 WOT 2=80 Stalled up max 175 WOT 1=80 Stalled up max 275ish, again about 80% throttle When I was backing the trailer up the other day, the truck was up to full running temp and I was at maybe 30-40% throttle when I felt the shudder. I'm wondering if there might be a sticky valve that wasn't letting pressure come up, but today it did? [/QUOTE]
