Well, lets do something else.

as a transmission I'm using 5 speed automatic from Mercedes.
Some will straight think that NAG-1. Close.
Same 5-stronic family but when Nag-1 actually is W5A580 (580Nm of torque rating) mine is W5A900, biggest and baddest of them all.

Used on AMG 65, Maybach 57 & 62 and SLR McLaren super car. This came out of rear ended Maybach at Florida.

I'm controlling it with Danish-made Of gear-controller, shifter out of e46 BWM, paddles of of AMG. More that later date.

Some many remember old picture like from 10 years ago that I posted about mating engine and trans with plywood adapter. That was just to get them hang to chassis when I was building it. Well, time and machines has changed some degree from those days.

At work place I studied how to use our 3D measuring arm, how to get points straight to our tool path program (Surfcam). It tells you the locations of the bolts, center of the crank, the hight difference of the flexplate vs block suface, converter bolt flance vs trans bolting surface. 'You even can get the shape of the block and trans housing if you like. As you can see on the photo I did copy some of the shade.

Took my engine block and trans with me one day and got to work.

Side story:
Social media showed its good side again. Was watching drag week live and saw Canadian team racing with grey twin turbo SRT-10 Ram, trans was out and I could see a orange flex plate bolted at back of the engine. Got me thinking.

Contacted the guy through Instagram and asked about it. He was kind enough to give me the contact info of the shop that makes them in California. Long story short, year later I got a custom SFI-proof flex plate between Viper and my trans.

Just needed to ream just a bit bolt holes bigger for ARP bolts.

Machined locator bolts for the block side, (normal unc-bolts with locator hole drilled on the head) and locator pins for the trans bolt holes. That way the measuring arms measuring pointy pen thing will always be in the center and right depth of every hole.

When design was right, upload the files, sourced material and needed tools to Haas-mill and pressed the green button.

Have to say the feeling was unreal when the adapter plate just slided on the dovels on the block the first time. The trans went in also like it was intended that way. I did machine an test piece, went to back of the cranks trans axle bearing housing w/ pointy head. Put that pointy thing back to trans oil pump "axle" to verified that everything was ok. Used dial-indicator and turned then test piece inside the mains and see are those two centric to each other.

Next the trans will go to get overhauled and upgraded, converter gets to be upgraded as well. keeping it as stock stall but have to fix the lock up problem that all 5-stronic converters have. Lock clutch is riding on just a little bit all the time. It need a kid of plate spring to be put in and all the vein solderd on, not just stamped.

Something else on next post....
