No problem glad you got it fixed.

 

Alan,

Well I thought I had it fixed, but still have an occasional slip.

I did not add the bottle of lubeguard you mentioned.

The parts store guy told me that their were several brands of it.

What kind do I need?

Then you have something else wrong. The lubeguard will not prevent slippage it just frees up valves and extends fluid life.
Are you sure it's full? I like to run aod's overfull, I fill them to the D in Don't.

You may have a worn transmission but there is one more thing that may help.
The control cable, at the throttle body, has an adjustment feartue that changes the pump pressure in the transmisson vs. throttle opening.
There is a clip and slot arangement that allows the cable housing position to be changed.
What you would do is shorten the cable "pull" a small amount like 1/8 to 3/16" by changing the cable outer housing position.
You must be very careful about this and not run the setting to loose or the bands and clutches don't get enough pressure, servo clamping and will slip and burn, then you are out a trans.
If you get it to short, the trans will shift very firm or if there is internal damage, it still won't work correctly.
If you feel the engine rev in OD , then the OD band is slipping.
I noticed you had put F type fluid in before, so get the right info before you do things that might be incorrect.
Only the power steering uses F type fluid.
Good luck.

 

Alan,

I will give it a try.

Thanks for the quick response!!!

I dont use it for hauling heavy loads,not even a quarter ton.

I have a 75 F100 4x4 that I use for my masonry work.

Owned it for 5 years and only had to do regular routine maintenance.

It has a 360 engine with a granny 4 speed. Great worktruck!

Its only a half ton but I have hauled up to 2 tons with no problem several times.

The 4 wheel drive works wonderful also for an old truck.

Bluegrass,

I will try the extra fluid first and see what happens.

It shifts out smoothly in all gears, but shifting to O/D is not quite as smooth but not harsh. Only a very very slight difference.

Thanks for the advice.

Im a big fan of Bluegrass music also.

I love Lester and Earl, Ralph Stanley, and many others.

Did you disconnect the battery to reset the PCM? That will erase your aunt's driving habbits, and only learn yours.

Also, keep in mind this is an electronic trans with a coast clutch that will disengage when you coast. At slow speeds the engine will rev faster thant the clutch will engage, which feels like a slip.

 

No we are dealing with an aod here, the throttle cable is the only external controls.

 

brickmason, you got it. www.afba.org.

 

I see that now, it was clearly stated too. Sorry I missed it.
