put the transfer case in 4x4 and put it in gear
You need a different frame, trans, transfer case, drive shaft, front axle.
you will need to swap the output shaft and tail housing from the old 4x4 transmission to the 2wd tranny which requires complete disassemble and then reassemble of the transmission
They will fit on a 4x4, not on a 2wd.They will fit on a 4x4, not on a 2wd.
Automatic trannys are different. The tail shaft on a 2wd tranny is different than a 4wd because of the transfercase. If in fact the 2wd manual tranny does not fit a 4wd you can always change the tail shaft to make it work.
No it will not. The center shaft in the 4x4 transmissions are longer so the transfur case will fit on it. You can take the center shaft out of the 2-wheel trans and install it in the 4x4 trans. and it will work. But that requires taking both transmissions compleatly apart. Sorry but what you want to do will not work.
No, they are all 2WD.
You don't! the NP249 in your grand has only 4 high neutral and 4 low. 2wd isn't an option. Correct, but you could remove the front drive shaft from the transfer case.
most vehicles only have 3 positions for transfer case. these are 4x4 high 4x4 low and 2 wheel drive
If your Trailblazer is a 4x4 the switch should be to the left of the radio on the dash.
If it has lock out hubs, Then you have a bad lock out on one side are the other. If it does not, Then the Actuator on the front housing is not ingaugeing. Need to check that with a test light. If it has power going to it , Then replace 4x4 Actuator. If no power then check 4x4 fuse in fuse box.
NO. NO. The reason you can't is because the center shaft in a 2-wheel drive transmission is shorter then a 4-whell drive transmission. The 4-wheel drive trans. has a transfur case that slides over the center shaft, so the shaft must be longer.
