ok guys no lockup at all
 

My buddies 47rh won't lockup even with manual lock switch?
Took pan off changed cylenoids and they engage when u flip switch so why wouldn't it lock tried everything:scare2:?

no lockup at all with a manual switch. . .

well, not that I have really any experience with these things, but if everything that should make a part do something works, and you've checked that it all works, and that does not do that something when told to, I'd be looking into that parts integrity.

Basically, I'd be seeing if the tq still has the ability in itself to fully lock.

However, if I were you, I'd wait for a more reliable person than I.

trans temp sensor on the line coming out of the trans. it wont shift till its warm and if that sensor is broke it wont shift into OD or lockup ever.

I bypassed that with a 1k resistor ... Ive tried the basics

It goes in o/d:tu:

Slim... You may be the only guy in history thats switched from ford to cummins and didn't like it ... Whats wrong with your truck???? Must be a turd to make u want a ford:pca1:

My Ford was a bigger basket case when I bought it than my Dodge.
But with the amount of time and effort I put in, I made it into a great truck, and that truck & I went through a fair bit in our travels.
The Dodge will go a long way to beat that.

Anyway, lets keep the discussion on your issue.

sounds like either a lock up solenoid or the clutch in torque converter is toast .....

when was the last time you had the transmission service done ?
what are your line pressures ?
have u checked to see if the OD button in dash is not faulty ?

any of these things could be going in ..... if it were me .... find a reputable trans shop and have them diag ur issue's and save u some unnecessary parts and such ... IMHO of course ..:tu:

O/d button work s changed fluid & filter maybe its converter although it still drives right

could have junk in VB .... thats what was happening with mine .... not I need to turn up line pressure just a biy more on the upper end ... shifts a bit late and loose ...

how do you turn the line pressure up on these?

little bolt on the vb
