hi first timer jus bought an 84 f250 6.9 w/ a 4 speed manual trans 4x4 i have very little knowledge of transmissions and need serious help i have a synchronizer going bad on trans and b4 i spent 400 bucks tried removing a plug on drivers side top part of trans and put half bottle of lucas oil trans slip fluid into it and when i put the plug back in it is stuck in reverse and i need the truck running it is my only source of income please help

 

is it a side shifter or top shift if it is a side shift check the shift deviderit stops the shifter from moving two levers at the same time top shift pull the shifter off check for broke parts in the shifter

 

Does it have an identity tag on it anywhere....... pics show on top bolts of shifter cover.

 

84 f250 6.9,
Welcome to FTE and the IDI diesel forum.

Did the plug have wires on it?

 

i believe its a borg warner t 19 an the piece i removed i found out was the pipe plug and i still have no clue wut i did

 

I have the T19 info manual with pics... if you would like it email me by clicking on my name (If your allowed to) subject: T19 trans.

 

my email is rocknroll5636@hotmail.com please email me the manual and pics thank you very much

 

i would like some advice because i was told my synchronizer finally went out that y it locked up and b4 i spend the money gettin a new one or a rebuild i want to make sure ive used all my options

 

Have you tried to shift it with engine running ...........or by rocking it clutch out.

 

How much play in the shifter?

Was anyone crawling around the shifter inside the truck?

Did you have the top cover plate that the shifter goes through loose?

 

The pipe plug you are talking about on the side of the tranny or on the top.

 

it is on the drivers side i think i might try rebuilding it myself if anyone has good internal pics of a t19 please email to me my email is the 7 post i think

 

t19 are easy to rebuild i had to rebuild mine to get a kit that comes with instuction u could try duble clucthing thats what i did for 6 mounth till i had mine rebuild the kit only cost me 185 in june

 

mine wont even move but in reverse tho wut is double clutching?

 

try shifting it into 1 with the truck off and them try to move have u check the axles or tcase
