T2180?

Recommended Posts

Who makes the T2180 Transmission?

What are the gear ratios 1-18????

Most important is the final ratio?

Can you determine the rear gears with the VIN? Has 44k rears.. VIN # 1M2AA14Y1SW054376

Thanks

Generally only the vehicle manufacturer, or their authorized agents, can tell you what rear ratios and suspension are in the truck by the VIN. they should be able to tell you everything about the truck from the VIN
