Hey all,
I'm thinking my 465 might be due for a rebuild but figured id run the symptoms past the forum before I jump to conclusions. When i bought my truck 2 years ago, everything seemed to work well but I had a different clutch at the time. I recall it being a little difficult to get the truck into second gear at speed which I understand is normal for these trucks, and I learned to compensate for that by double clutching.
However things changed last year when I added a new clutch. In another thread on this site we had theorized that the throwout bearing might be sized incorrectly as I have to have the clutch pedal all the way to the floor to fully disengage the clutch and this is with the best possible adjustment of the linkage. Its been my intent to take it back apart and remedy this but I just haven't gotten around to doing it yet. Since then I've been driving it and just putting the pedal all the way in for shifting however over the last year I'm noticing some worsening symptoms. It seems to be increasingly difficult to get the truck in second gear, even at a complete stop. For that reason, I typically start out in whatever gear the truck lets me into first but the second gear synchro is always reluctant to let me in unless im doing all of the rev match work for it. With 3.08 gears starting in low has never seemed impractical, and now im wondering if ive finished off an aged 2nd gear synchro by taking off in low fairly often on the street. When I go to shift from low to second, the shifter has started to occasionally grind/shake going into second if I dont get the RPMs just right which doesnt seem normal for a synchronized 2nd gear. It is by far the worst when the truck is cold. Yesterday before leaving my driveway the transmission didnt even want to spin down at all (clutch all a the way in) and thus creating a situation where i basically have to force it into gear. Yet once its warm it wont do this and it'll spin down in a few seconds. This seems backwards to me as I would expect if the clutch was dragging, cold fluid in the trans would resist spinning. On top of this, when its cold it will occasionally get stuck in first/low for no apparent reason. 3rd and 4th gear are issue free. It will shift into those gears like butter at just about any speed and temp even without fully pressing the clutch pedal.
Basically want to confirm my suspicions are correct that it is time for a rebuild or if there is anything else I should be considering here. Theres about 113k miles on this trans and its an old man truck that probably never opened the 4-barrel secondaries before i bought it. Any feedback is appreciated!
