Hi guys i own 2 sierras and am trying to make one good one.
The one with the straight body..the engine i couldnt get to run right might be due to carby or exhaust manifold cracks...doesn't matter
It had done 340000 kms the more banged up zook whos engine is going in the straight one has done 220000. My question is should i also swap the box over too ? The reason i hesitate is the low km zook has been flogged on a farm and i had trouble the other day getting it into 2h again after trying 4h and 4l.
Do gearboxes last ok? Is it easier to worry about it later on ??

Not sure which way to go

Thanks

Gearbox and transfer are totally separate- so your swapping between ranges issue has nothing to do with the gearbox, only the transfer case.

^ which the hard shifting between ranges is 99% of the time something simple like the shifter bush is worn.

Or wind up from using 4wd on a high traction surface.
