Could someone please help F150 diagnose his problem? He is not a troll--I directed him here from another site that we both frequent. He lives in Aruba and doesn't have access to all the technical info that the rest of us can get.

I am sure that he will be grateful and will check back often.

Thanks.

 

I'm sorry I didn't intruduce myself I'm jurgen from aruba. Dennis suggested me to post her. I'm taking the valvebody down now to clean it and look for stuck pistons. If that doesn't work. Its rebuilding time I guess

 

When you had the pan off, did you try the air checks that were suggested over on Toonuts racing forum? also, if you order the rebuild video suggested there, it shows a step by step rebuild and what/how the tranny is supposed to work. Less than $40, cheap and worth a lot more in valuable info. 3rd gear is applied by engaging the hi/rev drum clutches.

 

If you cleaned the governor did you replace the thimble strainer/filter when you re-installed it? Did you polish the valves?

 

Found the o-rings in the drums hard and britle and the one from the direct drum has a 5 mm gap. Doing a rebuild now.

 

Found the rubbers of the pistons in the drums hard en brittle! And a little piece about 5 mm* broken of in the o ring of the direct clutch. . So we think that's the culprit.

 

still bad news... its DOING THE SAMEEEEEEEE CRAP!!!!!!!!!!!!! what else could be wrong!!!!! the valve body is clean the whole transmission has new parts in it.. governor cleaned and cheked.. ( little screen also changed )

we had the trans in a thousand pieces cleaning EVERYTHING yesterday and its stilllll doing this?? come on!!

 

Did you replace the smaller seals in the drums that seal the ID of the pistons?

 

Did you replace the metal sealing rings and if so did they fit the drums correctly?

Did you install a separator plate gasket in the valve body?

Is the check ball in the direct piston?

 

yes yes yes yes yes to those questions...

remember this just starting doing in from a day to another.. so i didnt touch it when i started doing this..

could it be a bad case? cracked case?

 

noticed when i put it in Drive and press the gas halve throttle it will stretch 1st gear to 3000 rpm ish then shift to 3rd WTH !

 

well 3rd is completly gone now!


What the heck is going on?? where gonna take it down again and inspect and do anotherr air chek

only thing we didnt change is the converter and case

 

Neither convertor or case are the problem.


Air check everything, clean the valve body, install the correct separator plate gasket, make sure the governor is on correct and valves move freely, fit appropriate seals/rings.
Make sure the inner modulator valve is installed correctly and vacuum is hooked up and working.
Make sure the TV rod is not adjusted too far and returns properly.

 

valve body has been cleaned 3 times already.. i can take it down in like 10 minutes hehe..

yes were gonna take it down and do another air chek

i dont have the kickdown connected.. never had and it was running fine for about 3-4 months without it..

 

new TCI streetfighter valvebody and truck drives perfectly shifts in D and fiirm tire chirping shifts at WOT
