Forward clutch problem maybe??

i have an 01' F250 4R100 that on occasion when i put it in drive, i need to get the RPM's for it to engage. It only seems to do it after i have backed down or up a slight hill. I have been on level ground each time i put it back in D to move forward. It did it once last week after i backed my boat into the water on the ramp. It was time for a service so i did that as prescribed in the sticky with 20 qt of new fluid and a new filter. Well it just did it again after i backed up a long , slightly inclined driveway. I did put a john woods valve body in it 60K miles ago and at the time snapped one of the 10mm studs that is located in the corner of the valve body right next to another bolt. I didn't want to ruin anything so i just left it alone. made the mistake of use the ft/lb torque wrench and not the in/lb and learn. It has been working great for 60k miles which is why i left it alone. Ive owned my 6000lb boat all over the place, loads of stone and tile hundreds of miles over hills all with no problems ever. I have a 27 row 6.o cooler in it and my fluid has never gotten over 150 degrees. My pan was clean with no metal in it when i changed the filter with the normal small amount of "fuzz" on it. And hardly any. Any ideas what i should look at as fas as an easy fix or test to determine if its a solenoid or something. I hooked it up to a snap on scanner and there are no codes for it. It drives and shifts great while driving now. I tried to get it to duplicate the slip but i couldn't make it do it. Any ideas Mark??? hoping i don't need a new tranny.....cant afford that right now.

Thank you!

How does the fluid smell. Usually reving to engage is a leak which results in burn

I would be fixing that broken bolt on the valve body. Think of it like missing a headbolt and causing a head gasket leak.

You broke a valve body bolt and just left it alone?!?!?! And that's the only symptom you have? You're really lucky.

Pull the valve body, remove the broken bolt, and it will probably be fine.

Re: Forward clutch problem maybe??

Sounds like you are simply low on fluid, or you may have a shallow filter but have a deep pan ? Parts stores are notorious for selling the wrong filter when there are two options available, I seriously doubt the bolt you broke off has anything to do with it, the pressure regulator valve is in the pump, not the valvebody, I have seen the end of the filter with the grommet fall down out of the pump sometimes and can affect engagements if its sucking air, I normally move the magnet from the bottom of the pan to under the neck of the filter to keep it from falling down if the grommet shrinks over time.

I would first try overfilling it by a quart, maybe a quart and a half, if the problem goes away, then pull the pan and recheck the filter, also, when checking the fluid level if it looks low on one side of the stick and higher on the other side, always go by the lowest side.

Agreed, I don't think the bolt is the problem. If it was a leak it would do it all the time, or in the mornings or something.
