bronco II 5spd tranny problem

[jimmy3fingers]

'90 bronco II 4wd 5 spd This problem just started. Only occasionally while sitting still I have a problem getting it in gear. a litle jiggeling and it will go in. How do I check the tranny fluid and what kind ? transfer case too ? any ideas ? thanks , Jim

Welcome

I am by no means a transmission expert but I do have the same truck and same trans and occasionally mine used to be a beast to get into gear. I have read that it is the slave cylinder. I have been running Merc V in it (not sure what exactly was init before I got it) but the Merc V definately helped out in the cold whether - goes in much smoother now. The T-Case also takes Merc V - or at least that what I have been running since '08.

The fill/check and drain plug are on the driverside of the tranny - If I remember it is either a 19 or 21mm

Thanks mike....in fact it just started in the cold weather this year. so how much is full ?

 

[ragajungle]

I think it is about 2 1/2 Qts... I had 3 to start with and still had a bit left over. Do yourself a favor tho - get one of the filler spouts with the hose that screws on the end of a QT bottle - or a hand pump - it is kind of a squeeze to get in there -

yeah seriously, the hand pump is worth its weight in gold filling that sucker up

Also if there was the heavy gear oil in it (some ppl run 75w90 in them) you will have to change it out a couple times.

If it still sticks in cold whether you might need to look into getting the clutch and slave cyl re&re

 

[jimmy3fingers]

so do I fill it till it starts coming out the fill hole ? How do I gauge if it's full ?

 

[ragajungle]

yep. til the cup runeth over

 

[jimmy3fingers]

OK....other then that it always shifts fairly smoothly. I've noticed this problem only a couple times in the last 3 wks. about the time it got COLD ! i'm in north central ore. on the columbia river....having early winter.....thanks for all the input...Jim

 

[ragajungle]

make sure to stick around - lots of great info here

 

[jimmy3fingers]

I'm sure i'll have more questions. I just got rid of the fuel pump noise in the c.b. ....very pleased about that ! and ran across some nifty pic's for changing the electric fuel pump. I'm a fan of the manuel pumps like on my '84. ok...thanks for the help ...Jim
