when i put my 250 diesel ib reverse it sometimes(usually) stalls out? what would cause this to happen?

 

Seem's to me I have read another thread about this problem. Can't remember if I followed it all the way through or not. I'm suffering from oldtimer's disease, but I suspect the answer is here somewhere.

 

There are several possibilities. The most likely is low trans fluid. A loose internal filter can do it, and so can a sticky torque converter solenoid, control valve, worn pump, or a bad torque converter.

 

I can't find the tread just yet but remember another member having the same problems. Wound up being one of the wire under the steering column cover that was chaffed and when the selector was was moved, it grounded and killed the engine.
I look and see if I can find the thread.

Here's a few for your reading pleasure. Each has slightly differant symptoms and differant problems. Give a little more info on exactly what is happening and when and we'll go from there.

 

mine use to do it when fairly new but only when was cool out and only when first started
I can't remember when it stopped,been quite a while back

 

I had that happen to me and it turned out to be a bad pump in the trans. Does it die immediately when you put it in reverse, or can you put the selector in reverse but it dies when you give it throttle, like a clutch on a manual is being let out way too quickly and stalls the engine?

My problem was it felt like a clutch being let out too quickly and stalling it only when I would give it throttle. If it dies immediately when you put it in reverse, my guess is that it's something electrical. If that's the case, I would put the rear up on some jack stands to get the tires off the ground and eliminate the load on them to see if it will even go into reverse with no load. If it dies immediately then, I would start with electrical diagnosis.

 

Now I like this home self test. Good idea!

 

Thius could be as simple as low fluild in the tranny. the tranny requires oil to disenguage the torque converter clutch. why it picks on reverse first is unknown, it just seems to show up there. check your fluid level and or do a fluid and filter change. if you change your filter, take some time and break it open. it will tell you alot about the condition of your tranny.

It picks on reverse first because line pressure is higher in reverse. This places a bigger load on the pump. If the pump can't keep up the pressure control cuts flow to the torque converter to protect the clutches. The torque converter won't be hurt without fresh fluid for a while, but the clutches can die in a couple seconds if they lose pressure.
