Well I took a big breath and turned the pressure up on the 47re Friday. I also adjusted the light throttle shift. transmission still looked good inside with no big chunks of metal on the magnet. Not bad for 136K I guess. I have not put the gauges back on. Last time I did it solo, but I will get the wife to drive while I look this time.



My light throttle shifts went 1-2 now 8mph and 2-3 14 mph. This is still slower than my 95. I like it better each time I have increased the speed. How far can I go? I don't want this to make a hard shift with my fiver, but it would seem to me to be better on the transmission to hold the gears longer.

Won't tow untill Labor Day weekend so I don't know about lock up slippage yet. I think I'll tow that weekend before adding my usual shot of LubeGard.

I just watched a Two Guys Garage I had recorded where the BD guy showed the heat marks on alll three torque converters. The Allison even had heat cracks showing and BD said 5th gear is their weak point. Maybe that is why everyone of those trucks I have driven downshift to 4 so quick.

I also serviced my Dana 70 LSD for the first time since the disaster with the left carrier bearing and race. The tech used Castrol synthetic then. I went with Valvoline synthetic this time. I have not put any friction modifier in yet. Has anyone out there tried the Valvoline and did you need any FM?
 
Can you give me any info on how you went about turning up the pressure and adjusted light shifts? I'd like to see what it will do for mine. Any info is appreciated.
 
You can find the link on my previous post "47re-Turn up the pressure". SBrandon provided the link to dieseltrans.com. The thread is on page 4 of the 12V engine & transmission forum. There is good info on TDR and on dieseltransmissiontechnology.com about line pressure. I was still about 10# low on WOT line pressure and the adjustment yesterday should get me back to spec. I have not put the gauge on it yet.
