Hey all -- 87 silvarado blazer 305 TBI 700R4 np 205 32x12.5 3.10 Corp 10 bolt gov-lok (1) I'm getting some fairly hard shifts from 1st to 2nd (throw me back in the seat, raise the nose up). Most of the time it seems like the tranny's shifting late (high rpm in 1st) and I generally get a hard shift whether Im standing on the gas or not. Sometimes it will shift hard when cold and smooth out when warm ... other times it's vice versa. On a rare occasion i will get a hard shift from 2 to 1 when I decellerate gradually. Everything else is smooth as glass. Any thoughts? (2) Does my torque converter lockup in OD? I also have the large speed loss and engine bog before the downshift on slight inclines in OD. The tranny also wants to get into OD early depending on how far down the gas pedal is (45 going easy ... 55-60 pushing some) Any fixes (other than re-gearing)? my blazer came stock woth 31" and I don't think that 1" of tire diameter would make it shift that shitty on the highway. (3) I get a lot of "clunk" shifting into and out of gear ... I'm assuming with 150k and lots of links in the drivetrain it's just a little play. Anything to watch / worry about (I've checked U-joints)? (4) Any easy way to find out if the gov-lock is still working without pulling the diff cover? Thanks, and sorry for the variety.
