Advice on Allison V730 and VR731

First off Thank you in advance for any info

I am new to buses and diesels so I am very uneducated in this department.

I am having a transmission issue. The Trans light turns on every other time i drive the bus

I will probably need a rebuild anyways because the gearing is for low inner city speeds. And I need more speed!!!! top speed is around 55-60

don't know the gearing.

I would like to be able to cruse at highway speeds and not be screaming down the road.

anyways the transmission that is in the bus is an Allison V730

I found a rebuilt Allison VR731 and a VR731-RH for $900 each

I don't know if that will link up with my 81' 6V92T

would like to know if one of these transmissions would work and if they would give me more top speed.

My bus is a GMS RTSII-04. Its a pusher and the transmission is on the Passenger side (right side if you are looking from the Rear)

Thanks Again

Top road speed is controlled by the rear axle gears

Low number rear axle speed requires more horse power. I think new rear axle gears are still available. frank
