new transmission questions

[toomanymodz]

My new transmission has the letters 408G on the bellhousing, whereas my other transmission has 409G. Does this signify anything? Also, both trans mount threads were heli-coiled and not all the way through either. So once I bolt up the transmission mount, the threads will have about 1/2 inch of engagement. The bolts are really loose threading into the threads too. Should I be concerned about this?

408 and 409 means nothing. Very common to Heli Coil Transmission mount bolt holes. Most cores have damage to the trans mount holes. The mount bolts should be 10MM if trying to use 3/8 they will be loose.

Ok cool. Good to know. It came with bolts and they thread all the way in, but very loose. I tried 10MM and it would start to jam up and spin the heli-coil. So it looks like it's been threaded for 3/8. Hopefully it holds up when I go to torque the bolts.
