Well...

I don't know if the trans blew or not. I'm thinking no. The symptoms were that it felt like the engine was under a load in neutral, drive, anytime. Thing is, I found the harmonic balancer keyway to be really chewed up, which threw off timing for everything (the rings back there spin by the CPS). I'm thinking this was the issue. This could be dealt with by having the L67 balancer rebalanced to match the stock LN3 balancer.

The LN3 was supercharged at 152k miles, and I ended the season at 172k. Oil reports from Blackstone Labs concluded there was no real amount of added wear. No loss of compression, no increase in oil consumption (which was almost zero to begin with). I don't think the engine internals are worth worrying about.

so was there a vibration in the engine the whole time, because if it wasnt balanced as it should there should be a vibration.

It did vibrate a little more than usual at idle.

I've been busy working a lot lately, but I've had some time and have been working on the clutch pedal this afternoon. Expect an update soon with some pix

Unmodified G6 clutch pedal assembly





"Thingy" cut off





The nightmare under the dash. Somewhere, the clutch pedal has to be mounted here, in a good spot, and not interfere with the steering column



Notice where the "thingy" was coming in contact



Stock Reatta brake pedal



G6 clutch pedal on the left, and my Reatta brake pedal after some time with the angle grinder. I've got it really really close to being the same as the G6 pedal. It isn't perfect but the pad from the G6 will fit it just fine and it'll look like it'* supposed to be there.



And a lot of cutting...

I've added captions to the pix above.

Today I spent some time working on a bracket for the clutch pedal. Not quite complete but it should would out pretty well. I may have the angle of the pad on the clutch pedal adjusted (cut and rewelded) cuz I believe its different from the brake pedal. Or I could do the brake pedal. Guess I'll figure that out when I get it drivable and will do whichever feels best.

Console shift autos are pretty cool , though you don't get to use it much

I figure you guys can at least use the info I'll have to use on like the clutch and stuff, and the general things you have to do for a project like this

Starting to wonder if it would be possible on my Bonneville? I am sure the PCM tuning would be a giant hurdle though, I honestly think GM missed the boat by not offering a manual in these cars.
