#Pro shifted installBoth knocking off the old stuff to make a collar to install the new rings. It was previously Proshifted and now it is faceplated. Here is a side by side comparison with the modified part being on the left:Ĭlick to expand.I know exactly why my toploader needed additional machining and it may have been due to the input shaft that I sent. Since I had access to the machine shop at work, I used a carbide cutter and trimmed off part of the old cone. A quick call to Paul at Liberty confirmed that I needed to either shave some of the old sychro cone off the input shaft OR at least notch it to allow the output shaft to be installed. At first it couldn't be done as the input shaft needed installed from inside the case and that left inadequate room for the output shaft to be installed behind it. I spent most of the week trying to install the new guts into the case. The unmachined areas are a larger diameter than the Ford offering. This one is just as nice as the first one that I bought from him. Since then I received a new output shaft from David Kee. They asked me what I wanted to do with the shaft and I decided that they could keep it since there was no charges involved. Liberty called and told me that when they tested the output shaft for cracks, they found one where #3 gear is. Here is a business end of a factory type toploader gear that is used with a sychro and a brass blocking ring:Īn update. #Pro shifted plusIn his thread I hope to show through the use of pictures the differences of these 2 techniques plus reveal a few other things that I discovered in the original Liberty prepped toploader. See Liberty Face Plate vs Proshift for further details on these 2 techniques. I could have had 2nd, 3rd, and 4th Proshifted again, but that modification is not as long lasting as Faceplating and it is has less of a chance of surviving on the street. OK for an occasional jaunt, but not for a daily driver. It is possible to drive a Faceplated or Proshifted tranny on the street, but it requires a combination of double clutching and rpm matching. Engagement can be harsh and the higher the shift RPM, the smoother the shift. #Pro shifted upgradeAs an upgrade to the old stuff, I had the 3rd and 4th gear Faceplated and since it is not offered for 2nd gear, I had them replace the old worn Proshift ring with a fresh one.Īccording to Liberty, the reason for Faceplating or Proshifting is to "eliminate the need to worry about missed shifts." Faceplating and Proshifting eliminate the synchronizers used in common street transmissions and for this reason are only recommended for track cars. I recently sent some parts to Liberty to have them modified to replace the damaged parts.
