Pulling 4r100 Trans Need Some Pointers

[New2PSD]

I've got just about everything disconnected from the transmission with the exception of one bolt that I left in the bellhousing to keep it together for now.

I couldn't find the speedo cable, is that not in the trans on a 4r100? I read in the E40D instructions to disconnect the speedo cable. I've crawled all over this thing and can't find it.

I've got a jack under the transfer case and I'm trying to position my ATV jack under the trans pan which is where I need some help. Is the trans mount the center of gravity for the transmission and transfer case assembly?

I'm concerned that if I position my ATV jack forward or rearward too far then it will tip over.

I'm considering attaching ratcheting tie-downs to the frame strung across the vehicle near the front of the trans and rear of transfer case in order to stabilize it, anyone ever tried this before?

On both the super duty and OBS trucks the speed is taken electronically from a sensor on the rear differential. IIRC the only cable to the trans is on the drivers side for the multi position lever sensor, ie gear selector. Everything else should be electric. Not sure about the jack positioning.

Great, thanks!

Put your jack under the trans and put a strap around it then pull it out. That how I do mine.

What kind of jack do you use and where does it contact the trans?

Do you pull the transfer case with the trans?

[New2PSD]

Well it came out, no problem. Ended up not using the straps except to hold it to the jack.

I used the ATV jack at 90 degrees to the trans, one rail on the trans mount and one on the bottom of the trans pan with some wooden blocks to shim it up.

I pulled the transfer case along with the trans because that's what others had recommended but after doing it once I think it might have been easier to pull the transfer case and trans seperately.

Would you guys put the trans back in and then the transfer case? I don't see any reason not to do them separately, alot less weight to try and balance.

Put them in seperatly, less dangerous.

So what was wrong with your trans? Mine only goes in reverse; and
not sure if it is just electrial; or internal!!

Mine is slipping severely in drive. I could get it to go forward but just about had to floor it to get it to budge. I'm fairly certain the forward clutch seals are toast.

By the time I got it backed into the carport it wouldn't even go forward anymore.

The fluid smells burnt.
