I installed this gearbox in a VS 304 1996 and the gearbox would not change gear, stuck in first gear.
Would this be related to ECU issue not compatible with this gearbox (not being a VS box) or is the gearbox fCCk?

What fault codes come up?
vss has fault code even if intermittent but sounds like it's in limp mode...when did conversion I didn't notice trans had it's own fused power source to accessories so when car was running it was stuck in 2nd gear only knew when checking codes obviously.
Is trans correct one to your ecu or memcal? Is it a conversion or just different transmission?
You work out what trans it's meant to have like 4hbd or 6hbd or whatever is correct?
Is oil clean or burnt?
Hard to offer advice if story missing pieces.

Given the original post was about a speed sensor cable not being long enough. I wonder if it has even been plugged in? I have seen this exact issue when the harness on the speed sensor was damaged.

The ECU shift maps a based on road speed vs engine load.
This has its advantages, but also disadvantages. Such as no VSS = no gear change, and trying to tune WOT commanded shift points in relation to the rpm you want it shifting at.
