Tko-600 pops out of 4th
Hey guys I just installed a brand new tko-600 transmission and new clutch kit from American powertrain into my 71 c10. It has maybe 50 miles on it but it keeps popping out of fourth gear. A couple times when the back pressure built up a little bit while going downhill and then also a couple times when the rpm's dropped too low. There also doesn't seem to be any resistance on the shifter to keep it in the 4th position as opposed to sliding up into neutral.... Does anyone have any ideas why this is happening or how to fix it? I would appreciate the help.
Thanks for any information Posted via Mobile Device |

For sure call them, there's a problem with the fork/synchro/blocker on 4th gear if it won't stay put.
