I have an interesting issue that arose during the fitment of my Tremec TKX gearbox….
If I backup a little, quite some time ago I cut the hole in my transmission tunnel for the gearshift location. I positioned the cutout in the correct location as described in my car’s assembly manual. Given that my preferred gearbox back then was a Toploader, which has now been changed to a TKX because of clearance issues for the Toploader, however the shifter location for both gearboxes is close enough to be identical. Should be all good, yes?
So, the hole exists in what I believed to be the correct location for both boxes. The suggested location of the shifter on the TKX is the mid location of the three available, however I now find that the tunnel hole and the ‘mid’ shifter location do not line up at all.
Talking with Brett (BJ’s snake), his TKO uses the centre position for the shifter. Looking at and comparing the shifter location dimensions for the TKO and the TKX, they are identical. But, my TKX needs the forward location, which requires the purchase of an adaptor.
What I can’t work out is where the difference is. Brett uses an SBF engine and a TKO; mine uses an SBF and a TKX. Overall dims for both setups should be identical. Mine however, is about 100mm (4”) different in the mid position. I even checked to see if my gearbox was a TR-6060 supplied by mistake. No, it’s a TKX, and the 6060’s 3 shifter locations are very close to the TKO and TKX anyway.
More information… I believe also that ERA 289 cars using SBFs (what else 😉
use the middle position shifter location.
The answer might be staring me in the face, but I can't see it - I am at a loss.... so, my question -
any ideas why my TKX shifter location is so different? It's not just a few mm, it's around 100mm / 4" !
Cheers!
