Engine/Transmission (1994 - 1998) 94' 2500 2wd pops out of O/D

My 2500 2wd automatic disengages overdrive at highway speeds (55-75mph) intermittenly. Problem evently would not allow transmission to go into o/d. Transmition shop checked the TSB's and replaced PCM, TCP and main computer which seemed to solve the problem for about a year ($1300). The problem has resurfaced (intermittenly of course). I am looking for the cause? Has any one else with the same truck experienced this problem?

Mine started doing the same thing about 9 months ago and I replaced the output speed sensor on the output shaft (rear) of the transmission, drivers side. Dodge had a problem with the old style sensors, you can buy a new sensor and wiring comes in package (new connector wires to old wiring harness at transmission). Hope this helps.
