Has anyone ever put one of the B&M Shift Improver kits in an E4OD? The kind that you have to pull the pan and valve body to install. I put one in my '95 F 350 4x4. Ever since I put it in I have had no overdrive. At this point I wish I never would have bothered putting it in. It improved the shifts in 1,2, and 3 in high range, but when I put it in low range when I am plowing snow, it shifts so hard it feels like the driveline is going to leave the truck.
Also, I installed it in the tow or RV mode. I didn't need the race mode. Just trying to firm up the shifts a little and prolong the clutch life a little and look what I get.
Called B&M about it and they said it probably would be the solenoid valve body. Said to take it to a shop and see if they could pull any codes from it to find out for sure. Haven't gotten around to it yet.
