This will tell you if the trans is working properly and if it does then a sensor is holding it up somewhere. Will the truck start if the shifter is in drive or reverse?

No the truck will not start when it is in r or d

So then it is a prob in the tranny I I have jumped the wires no change I any thing the tranny shop is saying the tranny is bad but the code was a 45 and when I look it up it shows a bad seloid for od does that mean I will have to buy a new tranny if so do u know were I can get info to put a manual in my truck thanks again for your time

If its a bad solenoid you have to drop the trans pan and valve body. don't let some trans shop try to sell you a rebuild because of a solenoid.

I would never swap to a manual but that is just my .02 by the time you spend the money for a complete swap and a good clutch you could have a good built auto. Did you ground the selinoid and see if the trans shifts into od. If the selonoid is bad that don't mean you need a trans rebuild.

I don't know were the od seliod is to ground! Is it hard to change out the selinoid I have never done that before any body have any pics thanks for letting me know I don't need a new tranny I kinda figured they were trying to get at me also thanks for letting me know your opinion on the manual tranny swap if I ground the selinoid and it shifts I guess I need to change it out can u let me know were the od selinoid is thanks for all your help

Just put a new selinoid in it still no shift any ideas

There should be an orange wire coming out of the tranny. When it has ground applied to it, the tranny should shift into OD.

On my old truck I finally got sick of the OD BS and mounted an old style floor mounted dimmer switch on the floor. One end of the switch went to ground, the other end went to the orange wire on the tranny. When I wanted OD I simply clicked the floor switch with my foot and the tranny went into OD, everytime. Trick was to remember to kick it out when coming to a stop. I added a light on the dash to remind me.

You could use this to test the tranny's OD. Extend the orange wire from the tranny into the cab, run it thru a switch to ground, go for a drive and flip the switch. If it goes into OD then the tranny is fine, if it doesn't then there is a problem in the tranny.

If that helps Id look in the how too section and adjust the bands as well.

1cowboy

Thanks it worked so that means I have a short in it right I think onemoparnut was telling me the same thing u guys r awesome I will look into adj the bands thanks again for all your help I love this site just reading and ask qs I am learning so much

1cowboy

Those bands just get lose over time or what and how often do u adjust them I am planning on adj them every time I change tranny filter or as needed what u think

1cowboy

By grounding the od selinode and mounting a switch in the cab will I be causing prob to my truck or tranny

Onemoparnut

It won't cause any problems at all just remember to turn od off when you stop.

johnny08

What happens if you leave it on when you stop???

Onemoparnut

When you take off again it will shift into od as soon as is shifts third. It will almost shift both gears at the same time.
