PROBLEM! Where do I start???? need help PLEASE!

[texasstroker]

I just bought another toy today and need some help.....

It is a 1994 FORD F-350 crew cab single wheel with the 7.3L IDI turbo diesel, automatic overdrive transmission and only a 134-k miles.

Truck had to be jumper off, runs good, but the alternator is making all kinds of noise and the gauge shows to be under 1/2 way while at idle. Went to test drive and the transmission did not want to shift then the truck died. Jumped it off and took it back. Bought it any way, too nice of a truck.

My question is, if the alternator is bad (and or batteries) would this cause it not to shift right??

Does anyone have a clue about this problem? Do I just start with the batteries and alternator and see or do I need to just do the tranny too?

Did you pull the dipstick for the trans to look at the fluid. Is the fluid brown or red. If it is brown it is burnt and needs to be changed.

Most likely your alternator is no good if it is making noise. Then it has a bad bearing and that is causing your noise. A bad bearing in an alternator will not allow the alternator to produce the power it is suppose to. Reason being the brushes inside will be out of alignment and could be rubbing.

Fluid looks fine, does not smell burt or anything out of the norm. other than maybe about a quart low.

Do you think the lack of proper out put from the alternator would cause the shifting problems?

I installed a new alternator and 2 fresh batteries and now the transmission shifts PERFECT!

The E4OD's get a signal from the IP, a voltage signal, depending on how much throttle you are giving it (to kick down, ect). If you had lower voltage it could have been throwing it off?

Glad you got it fixed
