    Something is very wrong in the transfer case. I don't know enough about transfer cases to tell you what's wrong, but it does not sound like anything is wrong with the transmission.

    I took the pan off of the transmission, no shavings, no burnt smell.
    I drained the transfer case, barely any fluid at all..and what was there was very dark.

    The only thing that confuses me, and I forgot to tell you, the OD light was blinking earlier. We were on our way home from a 120 mile round trip, the OD light started blinking about halfway back home, I didn't notice until we stopped at the gas station. When I started the truck back up it didn't come back on the rest of the way home, and shifted fine. We got home, it sat for 30 minutes and when we left home it still shifted fine. About 10 miles later I pressed down on the gas to go up hill and nothing, no power to the wheels at all. Shocked I thought I'd lost the driveline. Instinktively I put it in park, GRIND, I shut it off. I got out and looked, nothing odd on the outside of the truck, no OD light blinking. I shifted through the gears, nothing...I decided to see if the 4x4 would engage, at this point I thought if it's the transmission, nothing will happen anyway. I hit 4x4 low and GRIND again we had power to the wheels.

    I have a 1998 Expedition with a 4R100 transmission that is acting up on me.
    It's shifting at an extremely high RPM 1-2 and 2-3 but will cut the transmission out at about 5500 rpm, and grind when put into park...If I shut it off and put it in neutral change it from 2h to 4x4 low it will re-engage and let me do it all over again from 2h. Is it a dead transmission, or transfer case or what?
    When it's "disengaged" I hear a rustling noise coming from the connection between the two..I'm lost at this time, please help

    Ok thanks. The guy I bought the truck from said it had a new transmission with 25,000 miles with a triple disk converter and a shift kit. He said it was gettin real hot before he replaced it and now that this is happening and it's getting hot I thought maybe it's the same thing and that's what made me think it was something electrical. But I will have someone take a look at it.

    Hello hoping you can shed some light on my situation. Today after work I drove to the store put my truck in park and moved something from my truck to someone else's and left the truck running 5 minutes pass and I try to back out and it's like reverse is gone. I let it roll back and tried to go forward and it's barely moving I tried moving it from 1st to drive and no change. I finally got it slowly moving down the road then the transmission caught and drove but something was off and kinda slipping and there was no od. My aftermarket gauges stopped workin so I plugged in my edge programmer and the tft was 260 I pulled over and shut off the truck. Read my codes and they were p0478 p1212 p1211 p1783 p0741. I let the transmission get back down to 235 and finished my drive home. It got back up to 250 and was shifting perfectly fine.

    Hello mark through looking at the posts you seem to be the most knowledgeable and qualified for answering my question.Got a 01 f350 with auto trans 4x4 7.3..To go forward I got to push 3/4 the way down on gas to start off. Now if I drop down in 1st or 2ed has normal power, reverse has good power, so to drive I have to start out in 2ed and then drop in drive, still feels sluggish to me and shifts to soon so feels like and sounds like I'm always underpowered like I'm in to high a gear, only 89k on a 7.3 but I know it's pushed snow. So basically before I rip it out I just wanted to know if for some lucky chance it's something simple I've heard things about solenoids and things.Found a guy in PA who rebuilds transmissions and swaps gor yours&700 bucks for a working one. I know if I take it to the dealership time my tow it there and they look at it it's going to be around 500 off the bat so Will probably just switch..just wanted to reach out for a little advice On want to think it might be

    hey mark in having a issue with a recently rebuild 5r110. it will not shift into 3-5. it shifts very smooth 1-2,2-3. the kit came with a modified direct solenoid i replaced and also dropped the pan and installed the old one back. Reverse works fine and only codes that have appeared are p0730- ratio issue and p2700 application time.

    I try my best to stay away from. Had it towed up to the tranny shop that did the original work, 2 months ago, talked to them today they are thinking plugged transmission cooler lines. I just wouldn't think that could cause a transmission to not engage at all, I figure it needs to be torn down again cause something wasn't done right the first time. I was thinking it has to be something internal if it won't go into gear at all. If you have any advice on what could cause this type of issue I would really appreciate it I more than anything want to make sure they don't try and take me for any more money since I also got a 3 year warranty for their work and I need this truck to run good cause I have to basically live out of it for work in the upcoming months so I really want to make sure they don't just do a patch job and it gets fixed correctly this time. Thanks for any advice you can offer in advance. I apologize for this coming as 3 messages just wanted to give you the whole story.

    I finished all this up got the truck running again jumped in to put it into gear and nothing. The car won't go into gear at all I can run the shifter through the gears but none will engage. There is still throttle for all of them when I give I step on the accelerator not car won't budge. Occasionally Reverse won't even have throttle response when I step on the accelerator but some times it does. I tried every gear including 1 and 2 and did this is 4X4 and 2X4 no change.My question is, could I have caused this w/ the upgrades I did I never went near the transmission its one place
