    Who machines C3 apply plates these days?

    Maybe I should have given some context on this. The truck in question has 345,000 miles on it. I limped it very hard a few times at around 270,000 miles on a race tune and have dealt with a wounded transmission ever since but on a lower power level of course. This truck will realistically never...

    Who machines C3 apply plates these days?

    I see Xcallibur offers the plate machined to .425 or .386 inches thick. I thought the rule of thumb was no thinner than .400?

    Who machines C3 apply plates these days?

    I'm not in a time crunch so I could send my plate out to be machined or purchase one already machined and send mine in as a core if needed. Yes just wanting to add an extra friction and steel to correct what Allison/GM should have from the get go.

    Who machines C3 apply plates these days?

    I've got a parts transmission with a good set of C4s in it. While I've got my trans out for a front pump seal I want to put in a transgo kit and address the C3 clutch. Basically recreate the TTS C3 upgrade kit, for better or for worse. Is there anyone that machines or sells an already...

    LB7: SAC-style Injector Life

    This is very encouraging. This past week I had the opportunity to do some work to a 2004 LB7 that I had installed a set of SAC 45s in about 1 1/2 years ago. Neither the owner or I could remember the exact mileage at the time of the install but we both agreed the injectors have at least 40,000...

    LB7: SAC-style Injector Life

    I didn't take note of the pilot and main injection quantities but rather just the timing when logging mine. If you are at 3.7 degrees of pilot injection try 4.5 and see how it goes. For what it's worth I've borrowed the pilot quantity values of 1.5 in the idle areas like that of the LLY. Not...

    LB7: SAC-style Injector Life

    Time for the 500 mile review. First of all some balance rates: Cylinder 1: -1.3 Cylinder 2: -0.4 Cylinder 3: 0.3 Cylinder 4: -1.5 Cylinder 5: 0.2 Cylinder 6: 1.4 Cylinder 7: 0.3 Cylinder 8: 0.7 As I recall with the worn VCO nozzles cylinders 2 and 7 were both in the 7s at...

    LB7: SAC-style Injector Life

    The problem seems to be resolved. The LLY pilot quantity table starts shutting the pilot injection off about 200-300 rpm sooner than the LB7 table. Corrected that and made a small timing adjustment and it sounded much much happier. Has anyone tried the 600 rpm idle with SAC nozzles? I'm...

    LB7: SAC-style Injector Life

    Its my turn to get on board the SAC 45 band wagon. Just shy of 50,000 miles on stock reman injectors and it finally started smoking on a consistent basis. The balance rates were very meh but two cylinders in particular were both in the 7s at idle in park but I forget which two. I got SAC 45...

    LB7: Decent daily driver tune

    I just tried this tune today and it is very smooth. The power comes up so smooth it almost masks just how strong of a tune it really is. I never once saw any smoke either and the fuel mileage is looking encouraging. The only thing I changed was the fuel pressure table which is based on a LMM...
