Bolt size needed to mount the front inspection cover for a TH400
I just bought a 1970, Buick Skylark, GS 455 with a TH400 automatic transmission. It was missing the inspection cover for the flywheel/torque converter, so I ordered a new one. The problem is that it didn't come with the four bolts necessary to muont it and I don't know what size and thread I need. I have a tech manual for it and it just says they are "tapping screws". Do you happen to know the type, size and thread I would need to properly mount this inspection cover? Thanks

Jan 8, 2009 - I hope its just a bolt on thing like B and D tranny. Any help would be great. .... The 2.3l four banger from the accord or cl will fit the v6 j30 engine. Is that rite? ... Do not buy a '97 to '99 3.0CL transmission and expect it to work in yourAccord. It will bolt up to the .... Honda 1998-1999 Accord - (3.0L V6) - B7XA
The starters on some engines require the addition of shims to provide proper clearance between the starter pinion gear and the flywheel. These shims are available in 0.015 in. (0.4mm) sizes from Buick, Oldsmobile and Pontiac dealers. Flat washers can be used if shims are unavailable.
Important: disconnect the negative battery cable before proceeding.
Raise the vehicle to a convenient working height and safely support it with jackstands.
Remove the exhaust crossover pipe.
Disconnect all wiring from the starter solenoid. Replace each nut as the connector is removed, as thread sizes differ from connector to connector. Tag the wires for later connection.
Remove the flywheel housing cover and disconnect the oil cooler lines at the transmission, if necessary.
Starter removal on certain models may necessitate the removal of the frame support. This support runs from the corner of the frame to the front crossmember. To remove:
Loosen the mounting bolt that attaches the support to the corner of the frame.
Loosen and remove the mounting bolt that attaches the support to the front crossmember and then swing the support out of the way.
Install the crossmember and mounting bolts. Torque the bolts to 80 ft. lbs. (109 Nm).
Remove the front bracket from the starter and the two mounting bolts. On engines with a starter solenoid heat shield, remove the front bracket upper bolt and detach the bracket from the starter.
Remove the front bracket bolt or nut. Lower the starter front end first, then remove the unit from the vehicle.
Installation is the reverse of removal. Make sure that any shims removed are replaced (please refer to the shimming procedure). Torque the two mounting bolts to 25-35 ft. lbs. (34-48 Nm). Connect the starter wires and install heat shields if removed.
You will need to raise the vehicle. On the drivers side is the trans pan. Remove the bolts,start on the rear and work around to the front. Leave 1 bolt in the front so the pan does not fall and cover you in fluid. Slowly loosen the last bolt, let the trans drain. If the pan is stuck gently pry it down to loosen it. Remove the last bolt. The filter will pull down. The filter has a seal up inside the trans. Remove it. Reinstall the new seal ans reassemble. Good Luck.
Tou can use any olds pont or buick 350 out of an earlier car that had a V-8. you can also install a 400 using a crossmember from a car that had a200r4 tranny in it. providing your car has a frame mount welded in on the left frame rail. otherwise you have to relocate the tranny mount on the exsisting crossmember.
I have an 81 buick that now has a455 olds with a th400 in it, I asol have an 80 cutlass with a 403 and th350 from a 78 pont wagon in it
the trick is to use the non lock-up version of the TH350.
