Hello everyone, this is my first post on this forum, great place to lurk, seems to have tons of info. But anyways I have a 84 El Camino with a mildly built 350 and a turbo350 tranny with a b&m ratchet shifter. I recently drove my el camino from Utah to Nevada, about 500 miles. before the drive I went through and did new spark plugs, belts and fluids. After about 150 miles i heard a slight ticking from the tranny and it disengaged, so i pulled over, checked the fluid and gave it a look over, discovered 2 of the bell housing bolts were loose. So i tightened them up and on i went. Made it another 100 or so miles and it did it again, put a bit more torque on the bell housing bolts and continued. This is when she started really acting up, about 300 miles into the trip i stopped for fuel, as i started my car to leave the gas station i could not get it to shift into gear, messed around with the b&m to no avail, so pushed it to a parking place and let it sit a few hours, after trying and trying i finally got it to find drive, started driving and quickly realized it would no get out of second, so i limped her in second (dont worry wasnt pushing it hard) and made it to the next big town where i limped to a napa garage, had the technician take a look at it and my timing was off, so he fixed that and managed it to find drive and shift some what normal (although tranny seemed a bit weak) So drove it another few miles til i was about 80 miles from my destination, stopped for gas and couldnt get it to find drive, or any other gear for that matter. After a while i was able to find drive and limped to my destination (shifted into all the gears) upon reaching my destination i parked it for a few weeks. Now here i sit trying to figure out whats wrong. If it sits for a good week or 2, it will start right up and find all the gears and shift perfectly, but as you drive it it progressively worsens, after driving a few miles if you take it out of gear it wont find it again. I am thinking it has something to do with vacuum, but who knows. Sorry for the lengthy post, just wanted to proved clear information. Thanks
