Hi guys not sure if this is the right place to post this but I've been trying to get help but can't find any on Google or YouTube.

 

I've purchased a 2005 ba xr6 off my mate,when he owned it he dropped the cradle and diff out to install a spool,once he fitted the cradle back into the car he tried to test drive it and for some reason it's stuck in first gear🤦

He had a scan tool put onto it and no codes came up he even swapped out the btr thinking it was the issue and still the same problem.

Just asking if anyone has experienced this problem in here and found a solution to fix it any help would be much appreciated thankyou🤘

well, the diff/cradle has nothing to do with the gear selection... and if it still has the same fault in terms of being stuck between actual gearboxes, unless they both had the exact same hardware problem, then it's likely you have an electrical command being sent to the gearbox that's telling it to stay in first. Go to a gearbox specialist for diagnosis.

Can speed sensors also cause this issue?

not that I know of.
