sm465 noises and trouble with 2nd gear
Recently i installed a freshly rebuilt sm465 into my cj5. Well after driving it for a while (bout 25 miles), i've noticed a few things that kinda of worry me. First, its grinds when you try and down shift into 2nd (the first syncronised gear), it has new snychros, and i know i put the synchro in. Going from 1st to 2nd is fine, but that is at really low speeds. Next is how much my engine speed drops when the clutch is engaged compared to when its not, say atleast 100 rpm, i kind of figure this is becuase its freshly rebuilt and very tight, but i would like someone to concure on this, and lastly it makes a sound like some teeth are making contact, a clicky clicky clicky sound when i push the clutch in and stop while leaving it in gear. If i take it out of gear, it doesnt make these sounds. Now i rebuilt this transmission under the guidance of an old mechanic who has rebuild several of these trannys, and he simples says let it break in, its a truck tranny, it will get better. Are any of these problems something to worry about?
