    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

    Hey I'm still having issues with my 4r100 its an e 99 7.3l with 474k been in and out of the trans a couple times its working but doest feel like it used to I changed the rear half of the pump... I'm concerned the tc is to blame... Cause in od climbing a hill chip at 90hp... It seems like its slipping a lil then unlocks it attempts to relock shortly after only to decide to unlock again due to slippage I assume...I haven't had the scanner hooked up yet... I dropped the pan today not much in it fluid was clean there was a lil bit of brass from a thrust washer I assume... Its got a Transco hd2 shift kit in it. Seems like its just in the converter tho to me. Everything was fine till I burnt up the 2nd gear clutches... I babied it for a week driving hiways 40 miles a day not sure if Ive damaged internals from that that I'm finding... Or if the converter is just failing... Its a RevMax heavy duty single clutch bilet converter any ideas what could be causing the slipping feeling?

    Hi Mark, I have a good one for you. my 95 7.3 died and it ended up being the IPR valve but in the process I did the HPOP. the truck started right up and runs mint now. all proud and happy I put it in drive and went to drive away and the rpms shot up as the truck inched forward. after diagnosis this is where I am at. 1)put it in drive and the truck starts of in 3rd. 2)put it in 2nd and the truck starts off in 2nd 3)put it in first and the truck starts off in 2nd. 4)reverse works good and is strong 5)the overdrive light will not light up (tested it and it works) 6)replaced the shift position sensor 7)hooked it up to a computer and drove it and it is not reading gears or gear shifts. I find it hard to believe this is coquicedence but what could the Hpop or ipr have to do with it?? could it be the wrong year IPR and screwing with the computer? please help

    I like Mobil 1 Synthetic ATF. I expect it will take 18 quarts.

    There is no need to fill the converter at all. Put 10 quarts in the trans and then start the engine. Let it run for ONE minute, then shut it off. Add five more quarts and start the engine again. Run the shifter through each position, then back to park. Check the level and use the remaining quarts to get the level right.

    Good morning, I'm looking for some e40d advice. I pulled my 95 ps to do maintenance and ready to put it back in. I have been running dinno atf and won't to switch to synthetic. I gave drained the tc, pan, all lines and coolers including the radiator. What fluid do you recommend and any specific procedure to filling/priming? Do I need to refill the tc prior to install thanks. JASON

    I just picked up my 99 F-350 7.3lit from the Trans. shop. the guy told me the warranty is not good till the body shop correctly installs the Trans. cooling system. Right now it is only connected to the Trans. cooler not the Radiator. is that correct? The truck was at the body shop to repair front end damage. The truck was at the Trans. shop because after picking up my truck from the body shop 500 miles later the tranny goes out. Checked the fluid level for the Trans. it was 1 1/2 qts low and smelled burnt. the fliud level was low because the Trans. fill tube was broken at the Trans. mount bracket. The lower part of the dip stick was the only thing holding the top half of the fill tube. Again the question is should the Trans. cooling system be connected to the radiator and the Trans. cooler?

    Thanks, Stretch
