    I just got a 73 blazer 350 automatic, it slips real bad in all forward gears,( about 2 mi. to hit 55mph) but reverse is ok. It has a new modulater valve, filter and new oil. I was told this is odd since low & reverse are in the same cluster. Is it time for a new trany or can someone make some other suggestion? Thanks for all replys. Tom

    If modulator is hooked up, fluid level is correct (checking it hot, after running it through all gears, right?) and it still slips, time for a rebuild. Yes, 1 and R use the same clutch pack. Not sure why, but R always seems to work : ) Perhaps just worn out seals, or clutch packs.

    No anti-theft measures on your truck? No pity when its stolen
