Question about Ranger Left Corrective Lens -8.0 by Zeagle

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?

Pic of starter on a 1989 Park avenue for replacement purposes

Gasoline Engines 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.
  1. Important: disconnect the negative battery cable before proceeding.
  2. Raise the vehicle to a convenient working height and safely support it with jackstands.
  3. Remove the exhaust crossover pipe.
  4. 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.
  5. Remove the flywheel housing cover and disconnect the oil cooler lines at the transmission, if necessary.
  6. 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:
    1. Loosen the mounting bolt that attaches the support to the corner of the frame.
    2. Loosen and remove the mounting bolt that attaches the support to the front crossmember and then swing the support out of the way.
    3. Install the crossmember and mounting bolts. Torque the bolts to 80 ft. lbs. (109 Nm).
  7. 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.
  8. Remove the front bracket bolt or nut. Lower the starter front end first, then remove the unit from the vehicle.
  9. 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.

How to replace filter (diagram maybe?) in 400 turbo automatic transmission thats sitting in a 1985 fleetwood southwind motorhome?

  1. Check the fluid level. The first thing to check if you suspect that the transmission is acting up is the automatic transmission fluid (ATF) level in the transmission itself. The dipstick on the TH400 can be found inside the engine bay, on the passenger side toward the firewall (opposite the radiator). Pull the handle attached to the dipstick, which will remove it from the dipstick tube. Clean any fluid off and put it back into place, making sure that it seats all the way. Then remove it again and look at the tip of the stick. There are level indicators there, which will tell you if the transmission is low on ATF.

  2. 2

    Check the linkages. The linkages that are connected to the shift lever can get out of alignment at times, causing sloppy or difficult shifter response. Look for abnormalities such as bent or broken parts, loose attachment points, or blockages that would prevent smooth shifting.

  3. 3

    Change the filter. Unbolt all 13 transmission pan bolts (on the bottom of the TH400) and remove the pan. The filter is found in this area of the transmission. Filter kits, which include the filter and a new pan gasket, can be found at any auto parts store. Replace the filter and fill the transmission with new ATF (the TH400 requires six quarts). Do not put the bolts back on too tightly, as the gasket can become damaged. Six to 8 foot-pounds should be plenty. If no torque-wrench is available, just put them on as tight as you can by hand, and then turn them 1/2 revolution.

  4. 4

    Inspect the cooler lines. The number-one killer of automatic transmissions is heat. If the cooler lines that come from the radiator are damaged or leaking, it might be necessary to replace them. These items can also be found at the local parts store.

Bought truck from private seller...3 months later cracked flywheel...replaced with new one...3 months later cracked flywheel again....need answers

you need to change the oil every 3 thousand miles and stay on top of your automatic transmission fluid. Keep the radiator full and make sure you are protected from freezing. Keep terminals clean on battery brushing away any trace of debris. As for the problem, perhaps your best bet would to be to carry a few spare flywheels in your trunk just in case a crack pops up again in one of them.
