88 ram 4x4 auto put trans in and it wont shift

the loss of power I was experiencing was because the secondary was not working. The vacuum was not strong enough to open the secondary.
I found a stronger vacuum and hooked it up there. Still need to fine tune the adjustments on the Carb. Have twice the power I had but still need adjusting.

ckeck linkage they might have undone iy and not put back in right place

is your fluid the right grade check shift linkage loose or worn or binding manual shift or bad shift fork or moter on automatic shift

Disconnect the shift linkage at the transmission and see if you can move the transmission lever into park manually. If you can't, then the internal trans linkage has a problem and pan will need to come down to find out why. If you can do this, then re-connect and adjust the linkage.Check any bushings on linkage pivot cranks...If a bushing is gone it may not be allowing linkage to move all the way to where it needs to go.

You say 'new' truck, 09? or new used? I have had 3 Fords, 3 w/ manual trans. case, if you go into 4x4 Low range, you must come to a complete stop before shifting the trans. case to 4x4 mode, and I always put trans (automatic) in neutral before slipping into 4x4, it engages smoothly, no grinding. 4x4 high range can be put in while moving, but I would let off the gas pedal, shift to 4x4 high range, then resume accelerating. If there is any grinding going on doing it as above, something isn't right. Check the trans. case fluid level also, to make sure that's not an issue.

Mr. dodge ram, with the 46re trans the pcm needs a signal from the tps sensor to monitor throtlle opening, accel and decel, what has happened the tps has a worn out spot in cruise area, hence the down shift, uphill is fine because your past the worn out spot, replace your tps sensor, its mount on left side of throtlle body , 2 screws, 1 connecter, and its out, when done turn key on, eng off, step on gas pedal 6 times slowly, then turn off key, this will help set min tps setting, GOOD LUCK RDJRP

sounds like you may have jamed the linkage. youll have to look underneath to see. back in hunting season i had a tire flip a stick into the linkage of my F-150. thought i had broke some thing till i look under and saw the stick. whew what a relief. when shifting in and out of 4x4 always put tranny in neutral and set parking brake. when shifting out you can move backwards slowly and out shift easier. gl

you could need a throttle linkage adjustment. first check to see if your ram will start in "park" and "neutral" only. if it starts in any other gear=faulty neutral safety switch. replace. ok, now check linkage for proper adjustment...with engine off and in park...remove intake housing..disconnect cableend from attatchment stud on your throttle body..slide cable off the stud (carefully)..verify that the transmissionthrottle lever is fully forward (idle) position..and verify that the lever on the throttle body is at curb idle pos..insert small screwdriver under edge of the retaining clip and remove..center the cable end on attatchment stud to within 0.04", or 1mm. install retaining clip onto cable housing..check cable adjustment..be sure trans throttle lever and throttlr body lever move in sync with each other.

Shifting linkage needs adjustment.

start car put it in neutral shift 4x4 lever into 4x4 low then drive a few feet. now shift main trans back to neutral then move 4x4 shifter back to 2wd high for normal driving then shift in drive and drive for a few min light should turn off..if nor disconnect battery for 15 min to reset computer and see if that does it. if that doesnt work you may need 4x4 linkage adjusted ..do you have a lift?
