Will a TB4.5L auto bolt up to a TB4.8L motor ?
its in a race car and the auto has been manualized.
Thanks

it prob will bolt up however there is more of an issue with getting the 4.8L motor to run
The 4.8L engines use an all in one ECU/TCU where as the older 4.5L use a ECU for the engine and a seperate TCU for the Auto box.
betting the 4.8L engine to run without the TCU connected is apparently hard work unless u get a seperate ECU to run the 4.8L engine

The GU 4 speed auto will definately bolt up to the TB48 & would be one of the best auto's to use in a TB48 powered comp truck or turbo/high power TB48 when built.
Kewish auto's in Dandenong Vic (03) 9793 2220 is a good place to go regarding the GU auto's.
Cheers

thanks guys.
I have the computer and loom for the 4.8l, so making it run should not be a problem.

The RE5R05A does run a seperate TCM. It's located inside the LH kick panel.

The tb48 5 speed auto's run a seperate gearbox controller. I've got one here. Wanted to run one in my patrol after a bit of research seemed like way to much stress as the hole lots inter connected, ecu, dash ignition barrel and gearbox controller. So went an aftermarket ecu and a manual gearbox from a tb42. The 4 speed auto will bolt up to the tb48, the gearbox's from behind the GU 4.5l being the pick of the bunch.
