I recently purchased all of the Marlin Crawler upgraded parts along with the Driftmotion 3-4 shift fork and a rebuild kit from suprastore.com.
I had a local shop rebuild the transmission and drove it for no more than 100 miles until a problem arose. I heard a loud squeal in 2nd gear and then in 3rd gear. When I came to a stop and tried to take off in 1st gear, the transmission made a loud grinding noise and kicked it out of gear. I was close to home and was able to limp it home in 2nd-4th gear, but there was a loud grinding noise while rolling in all of those gears as well. It didn't grind going into gear, just while it was in gear.
I took the transmission back to the shop and they told me that the Marlin Crawler 1st-2nd gear shift fork was too large and not made properly....which I find very, very hard to believe. They said that it was because the shift fork was too wide and it rubbed against 2nd gear, causing a lot of aluminum metal shavings to build up on the gears - which according to them is what caused my issue with the transmission kicking out of 1st gear and grinding in the other gears. They kept telling me that the transmission is "over shifting" second gear.
They said there's no chance that anything else can be wrong with the transmission and there's nothing that can be adjusted or installed incorrectly that would cause this and it is definitely the shift fork....I find this hard to believe because I have another R154 that has the IDENTICAL problem as the one they rebuilt but this one is 100% factory. I had removed the cases myself to find ZERO metal shavings in it although it was doing the same exact thing as the one I had them rebuild.
My question is what could be causing this problem? I find it odd that it happened to my stock one and then to a freshly rebuilt one with less than 100 miles on it.
Attached is a picture of the Marlin Crawler 1-2 shift fork and you can see where it has rubbed against 2nd gear.
Thanks in advance for any input and sorry if there is a blatantly obvious answer to this, transmissions are not my thing.
