Does anyone know the following to be true. I am interested in throwing the R452 overdrive gear in place of the 5th gear in an R150F to bring down my cruising speed on the highway/freeway. I will have it coupled with a 1UZ and 5.29's in the rear. Would I simply be able to replace this single gear, or would I need much more (the whole cluster etc...)
Also, has anyone been able to chase down a supplier/vendor for parts on these transmissions in the US?
Don't know but I'm trying to find out the exact same thing
