Water in trans in a c6 - 1986 Ford F 250

I would not use any one that has a transmission control module unless yours already has one. They do make TCMs aftermarket but you have to wire everything in and make sure its compatable for your application.

there is a censer on trans where shift cable ataches to trans there may be passing gear linkage to trottle body that has come lose or is missing

The fluid is not your problem.. you can change it without creating any problems.. at the same time change your trans oil filter.. when you take the pan off the amount of metal in it will give you an indication of the condition of your trans. Some metal is common.. lots of metal tells you a problem is comning. A certain amount is common because the trans clutches (the black stuff) and metals (silver stuff) wear as they are used. I think your truck.. C6 trans has a Modulator on it.. check that and check the vac line going to it.. Check to see if it has a pressure controll coming from the throttle valve.. C6 is one of the best trans ever produced.. (in my opinion)

direct clutches welded . needs trans overhaul

I believe only another 460 motor.

is your trans fluid low?

you may have a block trans air vent which may explain the blown seal and may also fect shifting

Tighten the band adjustment to 18 inch pounds it is a stud with a locking nut on the side of the transmission it is the one located toward the rear of the transmission not the one towards the front that is the 1st/reverse band adjust replace the modulator if problem persists sometimes they stick

are you looking for auto or manual trans? for a auto trans c4 or c5 or a c6 trans will fit and for manual trans AOD/AOT or E40D or a AODE-W(4R70W) will work aswell. have you heard about LMC? i get all my parts for my 1991 f-150 there. check it out get a free catalog everything you need for your truck you will find it there www.LMCTRUCK.com i hope this is of some help.

From 1990-1996 The C6 was replaced by the E4OD which was modified to include a fourth forward speed and electronic shift controls, replacing the hydraulic control mechanism of the C6.

The C6 works fine in your bronco.. Your friend will need a different transfer case!. i dont have the manual but this is my best guess. FOrd likes to make cars that have interchangeable parts. Like a 1999focus can interchange with 2007. as long as the liter and engine size are the same. In some cases. you will have to use different transfercase.

So you might be better off with a c6 transfer case or c4 for your friend.

Hope this helps
