What are the options for the rebuild/replacement of a transmission/gearbox for the 84-90 TRs?
From my 'disaster' thread a few years ago. I went with a rebuilt tranny from T Rutlands, installed by Ferrari of Central Florida. To this day the shifting is still smooth as butter. http://www.ferrarichat.com/forum/showpost.php?p=135980930&postcount=119 I also replaced the diff with the 512M version.
Dear Ferraristi, Testarob knows of what he speaks. He has had the disaster we all feared. Rob's main problem was the diff carrier split and cracked the case. If you need a rebuilt gearbox, TRutlands will be a good source. Don't forget to add Newman's diff if you're going this route. Newman has SOLVED the TR diff split problem. http://www.ferrarichat.com/forum/showthread.php?t=226140&highlight=TR+Diff What makes you think you need a rebuilt box? What problems are you having? Are you sure it's not just shifter / fork / alignment problem? Shamile Freeze....Miami Vice !
Take the other option also serious.... Get yourself a used 512TR gearbox instead.... they are available, like 512TR engines...
