I have a 1996 F250 EC LB4X4 Auto with 155,000 miles.
In 2004(at 48,000 miles) the transmission was pulled to replace a leaking front seal. While it was out a Trans-Go HD Shift Kit was installed with a LUK HD torque converter.
I installed a Tru-Cool 4590 and transmission temperature gauge also.
In the last year the OD light started flashing so I read the codes and had
P0381, P0741, P0755 and P1728.
Since clearing the codes, only the P1728 has returned. I have driven the truck weeks and hundreds of miles without it throwing a code.
Some days it will throw the code 10 times. I now drive it with the MT-2500 attached.
Can someone tell me what would be causing the P1728 code?
I had a chance to work on truck today. I fluid level is good and doesn't look burnt. I haven't had cooling issues since adding the cooler to it. I cleaned the VSS and the connector to it isn't corroded. The MT2500 scanner reads TCC solenoid stuck off.Can the codes P0741,P0755 and P1728 be caused by ATF in solenoid connector on transmission?
Live DATA reading shows PCM commanding solenoid A,B and TCC to open and close. Can a sticking solenoid cause the slip code if TCC is slow to lock up?
Need some help here, Thanks
