Hello. Thanks for the donation. Much appreciated

Some models are fitted with 4 torque convertor bolts?

TRANSMISSION
Removal & Installation ("C" & "K" Series)
Disconnect negative battery cable. Raise and support vehicle. Drain transmission fluid. Remove transmission filler tube, and plug opening. Disconnect shift linkage. Mark drive shaft(s) for reassembly reference, and remove from vehicle.
Remove exhaust crossover pipe for clearance, if necessary. Disconnect transmission cooler lines. Remove starter. Support transmission with transmission jack. Remove torque converter cover. Mark flexplate and torque converter for reassembly reference. Remove flexplate-to-torque converter bolts. Remove transmission rear mount.
Remove 2 heat shield-to-transmission bolts. Remove vent hose, fuel lines and electrical connectors from transmission. Remove transfer case shifter and position aside, if equipped. Remove transmission support braces. Note location of braces for reassembly reference.
NOTE:DO NOT stretch or damage any cables, wires or other components when lowering transmission.

Remove transmission-to-engine bolts. Note location of brackets or clips, and position them aside. Slide transmission straight back, off locating pins, and install Converter Holding Strap (J-21366). Remove transmission from vehicle.
To install, reverse removal procedure. Prior to torque converter bolt installation, ensure torque converter is against flexplate, and rotates freely by hand. Ensure all reference marks align. Tighten all bolts to specification. See TORQUE SPECIFICATIONS. Fill transmission with appropriate fluid. See appropriate SERVICING article.
