Welcome to this forum! It might be a disconnected shift cable or the internal Z link might have either gotten disconnected or bent.

not yet planning on doig that soon what are the chances two could do the same exact thing i mean there is no movement what so ever motor revs up when you put it in a gear park works put it on a hill and didnt move thought maybe it was the transfer case dont make any sense

thanks

It could also be a clogged front cooler or a defective torque converter. Did you clean the cooler or install a different torque converter prior to installing the second transmission?

 

[afsc]

please help

i have no gears put second tranny in same thing dont make any sense to me

If the vehicle is 4wd (which means it has a transfer case), then the culprit is probably the transfer case. Remove transfer case, spin the front output and the rear output should rotate in the same direction if everything is okay.

I've merged both treads together. Lets keep everything in one place.

if it was the transfer case when you shift it in to a gear and then back to park wouldnt it make a grinding noise

The cooler should always be cleaned before you install a new transmission or the junk from the previous transmission could get pushed into the new transmission, and clog it up. There is a special cleaner called cooler cleaner in a spray can. Here is my product review on it: http://www.explorerforum.com/reviewpost/showproduct.php/product/226/cat/500

Not necessarily, there is a "Neutral" point in the transfer case (that is between HI range and LO range) .. the shifting gear might be stuck in this neutral point.

this is a push button 4x4 not a floor shifter

You have to disconnect one line, run a hose into a bucket, then connect the other line to the spray can. The pressure from the can will push the junk out of the cooler. Since it was already connected to the transmission, I think that most of whatever was in there could already be in the second transmission.

thank you i will try it tomorrow

It doesnt matter -- "push button" or floor shifter", there is a Neutral point all transfer cases because there must be a neutral zone between HI and LO range or else you would never be able to switch from HI range to LO range w/o breaking gear teeth. Its like a manual transmission -- you must shift through the Neutral zone to go between 1 and 2. The only difference with a "push button" transfer case is that the transfer case shift motor does the shifting.

I mentioned it in post #8 of this thread -- second sentence .

If the vehicle is 4wd (which means it has a transfer case), then the culprit is probably the transfer case. Remove transfer case, spin the front output and the rear output should rotate in the same direction if everything is okay.

Sorry I should have said "spin the front input" -- spin the splined input shaft that engages the output shaft of the transmission, the rear output flange should spin if everything is okay.
