Having problems with a non-lockup th350...
Drops out of gear and only appears to be using 2 gears, don't know if it's skipping 1st, 2nd or not going into 3rd as this is a problem had since I bought the car. It's on a 400ci smallblock and the previous owner assumed it was running a 2 speed powerglide (as the original would have had)
Anyway i've ID'd the box as definitely a 350, with a 13 bolt pattern on the pan and the triangular corner missing. Not a 250 as there is no band adjuster by the cooler lines, and it's a non-lockup (no electrical connector on drivers side of box)
Put a new vacuum modulator on it last week, which is adjustable (although haven't messed with it yet) and it makes it shift smoother, but the problems still exist
Any ideas on what could cause the problems? Governor perhaps?
I don't know much about auto boxes and might just take it somewhere to be fixed, but need it done before Old Warden
Does anyone know of a good specialist in the SE area, perhaps in and oround London or Dartford/Gravesend way? Someone who could drive it and put their finger on it?
I tried Automatic Gearbox Specialists near Gravesend clock tower, they reckoned it probably needs a rebuild, but i'm not so sure
