Topic: R154 Information

[Noz]

Hi guys,

new here am a mkiv supra owner. I've emailed the MC team and waiting on a reply regarding details on rebuild components.

While going through the box rebuild process thought I'd join here.

Can't find any information on the forum regarding R154 boxes

Are they super uncommon here?

I think the R-154 gearbox was only offered in the supra. In the trucks the most common transmission is the R-150. They also used the R-151, but only for two years, only in the pickups and only behind the turbo motor. Fortunately I beleive most of the internals in R series transmissions are the same. Did your car come with the R-154 from the factory? Behind what motor? I thought that the supra had a six speed gearbox.

It came from a 1JZ mk3 supra. I'm looking to install it into a mk4, but wanted to have a box rebuild/upgrade before I installed it.

I'll do some research into the gearing, would be good news if the parts are the same as the R150 for ease of component selection.
