Hose size for transmission lines 2001 GU Auto

[Xtreme]

Hi all,

Does anyone know offhand the internal hose diameter for the 2 hoses that run from the transmission to the radiator? I need to buy a short length to loop them around and connect each other. Looks to be around 6mm?

Trans cooler hoses are 5/16"

[threedogs]

which would translate to 8mm

Trans cooler hoses are 5/16"

I should add that aftermarket trans coolers (my Davies Craig anyway) use 3/8"

would this be right for a 99 GU (4.5lt)
