DANA 20 HELP!!

[broncohacker]

I have a T-style transfercase on my 76 bronco, and i recently put in a 89 5.0, and NV 4500 conversion. ive been driving it to work..and snow wheeling so far for the past 4 months... BUT!.. i got a used t case cause i previously had the j style stock and the NV 4500 supposedly doesnt work with it. so i got THIS T-case and it looked ok when i had it apart, cause i had to put the new spud shaft to convert to the NV, alittle worn gears but nothing terrible looking. (then again i dont know much about gears and being 21 am a grean horn). but i know well enough what is "BAD". i cant individually shift the front and the back for starters, and the only way to get the front into 4h, the rear has to be engaged in high first.. :glare: SECOND ISSUE... the first wouldnt be too bad. i dont even know if it should? that was my whole excitement over it... but kinda off topic, my dad just built a 70 408 stroker bronco on dana 60s new paint ALOT of $-) something i dont have, and almost show worthy. he also has a t style case on a Np435 but we havent test drove it farther than the end of our drive way, and he wont let me touch it. so i dont trust him as a GREAT source either. MY FRONT ONLY SHIFTS NEUTRAL AND HIGH!! ( i havent pulled it apart again, since i drive it to work every day. but wanted to see if anyone had any ideas or MAYBE HEARD of someone besides me that has had this??

"i cant individually shift the front and the back for starters,"

You didn't say., but this sounds like you installed the "twin-stick" shifter.

"and the only way to get the front into 4h, the rear has to be engaged in high first.."

And this as well.

Best guess is there's something amiss in the linkage. You should be able to run HI/LO range front only ----- rear only ---- or both axles engaged HI/LO.

The J shifter would do the same with the shift shaft tabs cut. & the proper twin-sticks.

If you have the stock single "T" handle shifter, you don't have all those options.

Ahh im sorry. Yes I do have the twin stick set up. Sorry, left that out. Yeah I figured. We have a couple friends up here, almost a bronco club, with the same set up. I guess what u were saying about using the j case could work. I traded it from a friend, but I dont think he wouldn't be hard to get it back from. It was just SO much work doing the adaptor, and its gunna be a Bï+©ih tho take off so I've been avoiding the thought first.

Not suggesting "swapping out" unless there's an internal prob. with the "T" style 20 in there. The "T" style is "supposedly" the easier/better set-up.

You should be able to pull the (floorboard) covers & watch what's happening when you move the levers....starting fr. neutral on both.

Didn't the twins come with instructions...& shifting instructions as well..?

when putting in twin sticks, ther are 2 shift shafts in the t case, there are detents that hold the forks in place but there also detents between the shafts that prevent independent shifting, one shaft needs to be removed in order to remove the detents between the shafts, basically dissassembly of the whole t-case

I dont know about the t case but I had twin sticks on my j case and no matter what they need a little push and shove and a little rock and roll too engage sometimes. But its worth it too drive home in front wheel drive after you twist the rear shafts.
