Then you have made a big mistake and used the wrong fluid. Drain it all out including what is in the torque converter and put the correct fluid in.
No
I'd suggest using a Dextron III/Mercon automatic transmission fluid.
Dexron ATF
A 1986 Ford Bronco II would use R12 unless it has been converted
Kinda complicated You use the computer Located behind the seat (driver) You can look it up @www.autozone.com...
one is for gm and mercon is ford now days they make a dexron mercon mix acceptable to both Dexron III and Mercon V have different specs. You should not use Dexron III in place of Mercon V.
GM=Dexron, Ford=F, others see manual.
Dexron 3 is prefered.
Most Ford five speed transmissions use Dexron/Mercon ATF fluid.
The tool I most recommend to you is the professional mechanic. My pal Brett is pretty good. So is Steve. Use either box wrenches or ratchet and sockets.
dexron-mercon
If it is a A/T Powerglide, you can use Dexron or a synthetic such as Mobil 1 ATF. You may not be able to find Dexron, but you can use Dexron II or Dexron III.
