1995 Bronco stalls when put into drive

I have a 95 bronco, that until yesturday was running fine. I got in and put it into drive and then the engine just died. I put it back in neutral restarted and let it warm up. Put it back in drive and engine stalled again, engine will not run in drive. The fluid was a little low I added half a quart and still same result. I can put the truck in reverse and the truck runs like a dream but soon as I put it in drive again, stall. Any help would be appreciated. Thanks

Welcome to FTE dweb4! You're probably lacking way more ATF than the half qt. you put in. The ATF level has to be measured with the engine running at operating temp. while in Park, usually I would advice running around the block and driving around for a while before taking the measure but in your case that won't be possible. Once filled try moving the truck again, and remember checking the fluid at least once more later the same day, same procedure.

How did you measure the ATF level anyway?.

Just off of the top of my head, two thoughts.

Since it's OK in Reverse, that seems to say the IAC is OK.

1)Some electrical problem with the transmission range switch?

2)Engine torqueing on mounts causing an electrical or vacuum problem?
Of course the engine always turns the same way, CW as viewed from the front. For every action there is an equal and opposite reaction...
So when in Drive and foot on brake, the engine torques CCW (as viewed from the front) against the stopped driveshaft, since the trans output shaft would turn CW in all forward gears.
But when in Reverse, the driveshaft would turn CCW (as viewed from the front), so the engine would torque over in the CW direction... the opposite of when you are in Drive.
So, is there some electrical connection or vacuum connection that is opening up when the engine torques CCW? Maybe vac line to the MAP sensor, vac take-off to the brake booster, loose battery terminal, etc. etc.

Just some thoughts.

I just thought, what about a faulty MLPS? that would probably cause problems too.

Ok did a little work today and here is what I have now. Took truck out and it will drive again in reverse as well as 1st gear and once driving shift into second no problem I put into drive and truck will run but once I slow down in drive to under about 5mph the engine sputters and it goes into a stall. I checked the fluid it was ok, so I decided to change it anyway. Took pan off filter still attached to the trans, I put new filter, pan gasket and fluid in. Went back out same results. So I went and got a ford code reader and this is what I got:

Engine off codes: 157, 629

Engine on codes: 536, 538, 632

Please feel free to give me your comments and thoughts, if I can't solve it by tomorrow it's going to the shop.

Code 157 - Indicates a mass-air sensor fault. Assuming yours is indeed a mass-air equipped model, that is the root of your stalling problems. Replacement is the best course as repair is not typically advisable.

Code 629 (during the KOEO test) - indicates that the transfer case was engaged in a 4WD gear (HI or LO) during the KOEO test.

Code 629 (during the KOER test) indicates that the TOT (Transmission Overall Temperature) sensor was out of range (too cold) to perform the test. OR that the TOT sensor indicated high voltage back the to the ECM (meaning the the external temperature was less than -40 F....highly unlikely unless you live that far north or south).

Code 536 - Indicates that the operator did not step on the brake pedal during the KOER test. (If you did, and this Code still shows up, check your brake light switch for proper operation).

Code 538 - Indicates the operator did not perform the "goose test" during the KOER. This is the dynamic response portion of the test. There is no other reason for this Code to manifest.

Code 632 - Indicates that the operator did not de-activate/re-activate the Overdrive cancel switch during the KOER test.

Ok went back and pulled the codes again, after noticing I was missing steps, here is what I got now.

KOEO codes

157, and 629

KOER

no codes

I'm hoping it is just the mass-air sensor...

Best bet is to start your own new thread for whatever issue you are having.

edit: NVM...you already did https://www.ford-trucks.com/forums/1...-stalling.html
