Topic: t-case wont go into 4 low

[Dr.Maxwe001]

I have a gear driven 21 spline t-case  on my 93 toyota I put a 350 motor and a th350 trany to my t-case useing the adaptor that I bought I was told that I do not have to change the shift rails  I jacked the truck up and had all 4 tires off the ground I have use of 4 hi but not 4 low when I put it in 4 low it grinds its self out like you chant drive a 5 speed manual I cant figure out why I have 4 hi but not 4 low any ideas whould help  yes it is a fwd shift t-case the one that came stock in the 93 toy I already swaped the shifter out with a top shift shifter but I cant figure out why I cant get the darn thing to go into 4 low

[Duffil]

did the adapter have a hole to allow for the hi/low shift rod? and if not, did you cut it down?

[*ROKTOY*]

What he said

[Dr.Maxwe001 [OP]]

I dont think so I drmember it had a square hole on top of the adaptor that you put the shifter into from the top
however the shift rails on my t-case were poking out the front and went through my adaptor my shift rails sit in the top of the adaptor and my old style shifter that I have will shift it into 4 hi but not 4 low

PIC'S Needed

[MiniSimp]

I think this is the adapter, it does appear to have holes for the shift rails

[Dr.Maxwe001 [OP]]

yes thatis the adaptor and the shift rales are covered up in that pict but YES that is the adaptor i have

[MiniSimp]

Is there any chance that your shifter is hitting your body?

[Dr.Maxwe001 [OP]]

no

[kvn85]

You should call Advance Adapters.

[*ROKTOY*]

You could try removing the shifter and try putting it in 4lo by hand see if that works, I'm thinking there maybe some interference there or your shifter is not in properly. Another thing did you take the tcase apart and mabe forget the interlock pin?

[Dr.Maxwe001 [OP]]

I did what advanced adaptors told me to do and that was to mount the adaptor to the t-case thewn the whole unit t-case and adaptor to the trany use exsisting bolt holes that the t-case used /NO I did not take my t-case apart and look for a interlock pin advanced adaptors did say anything about taking the t-case apart and removing a interlock pin. I did what they told me to do

[Duffil]

unless you are twin sticked, you don't mess with the interlock pin.  it really sounds like the hi/low shift rod isn't moving all the way forward.  If you did not disassemble the case at all, and you are sure the shifter isn't hitting anything, you need to call AA.

[Dr.Maxwe001 [OP]]

I can hear it grinding the gears in 4 low and I know this cant be good so I put it back in netural on the t-case

do I have to have the trany in netural as well or can it be in drive with the break on or can I have it in park  or does it just got to be in netural to go into 4 low

[Duffil]

it should shift into low in any gear...

[Dr.Maxwe001 [OP]]

ok I just found the reciept from where I bought it and the part number is on it and here is the part number 50-5702 advanced adaptors

[Dr.Maxwe001 [OP]]

just got off the phone with A.A . and he told me that I didnt need to change the shift rails or anything but I could take the shifter off and manualy put it in 4 low and try it that way and see it it goes that way  now all I gota find out is what shift rail works the hi low side is it the one on the left or the right

[Duffil]

I just realized it's not the hi/lo rod, the one that moves forward is the 2/4 shift rod.  it is on the right hand side, looking down from the top.  it is the one that moves out of the tcase for engagement.  the hi/lo is actually the left rod, and moves backward to go into low. sorry. I would still pull it and verify that everything works fine out of the truck.

[Dr.Maxwe001 [OP]]

ok I pulled the shifter out and I manualy put it in the gear i did both shift rails independantly of each other  but now you tell me that both of the rails have to be all the way back for it to be in 4 low

[MiniSimp]

Well, you go down to go in to 4wd (right shift rail moves forward) then over to the right (stick moves to left shift rail) then forward one click to neutral (left shift rail moves back) then forward another click for 4 low (left shift rail moves back more). So then, with the right shift rail all the way forward, and the left shift rail all the way back, that should be 4 low. Unless I'm all fucked up.

[Dr.Maxwe001 [OP]]

so the one on the left (driver side) is all the way fwd. and the one on the right(pass. side) is all the way back    and that puts it in 4 low?

[MiniSimp]

I think so, I use a twin stick, so I'm not entirely sure, it's been a while since I used a regular shifter. Duffil will be able to say for sure.

no, the rail on the pass side should be all the way forward and the drivers rail is all the way back.  Minisimp is correct above.  You have to remember that the shifter pivots at a midway point, making everything under the pivot the reverse of the knob position.

[Dr.Maxwe001 [OP]]

so when I manualy put it in 4 low the pass side will be all the way to the front of the truck and the drivers side should be all the way back towards the tail gate correct?

[Duffil]

yes.

[Dr.Maxwe001 [OP]]

ok I will try this and see if i can get it to go either tonight if the rain holds off  other wise I will have to tryit tomarrow afternoon

[MiniSimp]

...if the rain holds off...

It rains inside your cab?

[Dr.Maxwe001 [OP]]

if i leave the sun roof open it does   but I gota have power to see and the extention cord will get wet and I dont like to use the water eletrical mixture to well while it is lightening outside or else i might look like this  

[Dr.Maxwe001 [OP]]

update: I got the shift rods to go all the way into 4 low and it didnt grind or anything so there for it is in my shfter itself, The shifter is stopping before the gear is fully in 4 low I guess the could be due to the fact that the old style shifter that I have the ball the rotates around is not as big/ (have as much movement) as the stock shifter??? I had so I gota figure out why its not putting it all the way in gear any ideas??? I might have to weld a small joint around the stub the moves the gears in and out unless you have a better idea???

[Duffil]

I've only seen one style of tcase shifter on the bottom.  What I mean is, from the ball down they are all the same.
