    I have a question for you. If I drive truck with the tranny stuck in 3 or 4th and manually shift it will this damage it? The truck is located 3 hrs from my house at a garage that had it for 3 weeks and I want to get it out of there. If I drive it back home Id be more confident with the mechanic that would fix it ( if I couldnt figure it out myself)

    It used to,since tapping the brake turned off the cruise. This is while going downhill.

    Hello Mark
    I am having an unusual issue with my 2009 V10 -auto trans.
    The cruise control will hold the transmission in a lower gear to hold speed downhill. Lately, I've noticed when I tap the brake,the transmission does not upshift. The cruise light goes off. If I turn the cruise off with the button,it shifts up.Any ideas?

    The pump did get taken apart during the rebuild and was correctly put back together would that have caused a problem?

    I was finally able to test the range for each gear. I will start with Idle. P range is 55-65 I recorded 70, R is 75-99 I recorded 86-90, N is 55-65 I recorded 68, D is 55-65 I recorded 68, 2 is 55-65 I recorded 62, 1 is 75-99 I recorded 90. High idle was done at 1900rpm. R is 240-265 I recorded 220, D is 156-174 I recorded 120, 2 is 156-174 I recorded 140, and 1 is 157-186 I recorded 180.

    Fluid is at 15.7 qts and the filter in the pan is correctly installed. I will have to get a pressure gauge and check for results. is there a specific pressure overall I am going to be looking for or does each gear have it's own pressure range

    Hello Mark.

    My name is Michael I am hoping that you might be able to help me out. I have a 93 E-350 with the E4OD. Before I rebuilt the transmission the issues that I had were delayed shifts in 2nd gear and overdrive seamed to be in a partial engagement. I just finished putting the transmission back in and went to take it for a test drive after letting it sit and run in park for 10-20 minutes to make sure all fluids have had time to circulate I check gears as I went down the column. I Found out that there seemed that there is no forward engagement. I also found that there is a little bit of a reverse in first but that is only if I have the rpm's up to 1500 and it inches backwards it's not a strong feel. I replaced all the clutch packs, the servo, the band, new filter, new torque converter, new solenoid pack and upgraded parts that were a weak point since I do a bit of towing.

    hi my name is Todd I have a question about my 97 Ford Powerstroke the other day I was driving down the road and the transmission acted like it went right into neutral I pulled the dipstick to check the fluid level it was good the fluid does not smell burnt or badso I thought it might be a power supply issue because my batteries were going out so I put new batteries in it that was not the issue so I change the tranny fluid and replace the filter and found a 30 amp fuse underneath the hood day goes to the transmission was blown replaced it and none of that work so I started to trace wires and check connections could not find anything wrong I don't understand what's going on here or if you have any advice it would be greatly appreciated
