Hello TMG,


Long time since we first crossed paths. I feel the same symptoms of hesitation between 1st and 2nd with my Hot Juice at times. Remove the Juice and do a few WOT runs and see if you feel the same hesitation without it. My tranny doesn't shudder though.


I'm picked up a Quad Stealth Tuner also, the 135 HP version. I am running it now and have the HJ in the toolbox. I like the way the Quad feels just running around town. It doesn't mess with the TCM, so the tranny shifts just like stock.


BTW, I remember how much you liked smoke. The Quad in 135 HP setting smokes allot more than the HJ. I just thought I would tempt you with that sidenote.Edited by: RV Guy

Mine forgets to shift in to 2nd once in a great while. But I think it's just that! I am sure a computer brain can have brain freeze, God knows I do!

I have experienced this as well. I was running the hot OJ as well. I experienced it twice. It almost feels like limp mode. I have not experienced it since. I have a feeling those tap cells get used very little. The TCM probably bumped up the pressure. I will tell you shortly if there is any internal damage.

Yes, any excessive slippage is bad, I say excessive because all tranny's slip, they have to, to shift, but after the shift there should not be any slippage. BTW I'll bet the shuddering is the Tq converter clutch slipping. At least that is what shudders in my tranny

I experienced this in all 4 of my Duramax/Allison Trucks. In June I purchased the newest one, an 03 and immediately towed my 26 foot 11,000 lb show car carrier to <st1:place><st1:City>Tulsa</st1:City>, <st1:State>OK</st1:State></st1:place> from <st1:City><st1:place>San Diego</st1:place></st1:City>. In total I drove 3500 miles in 2 weeks most of it on the highway in 5<SUP>th</SUP> gear. I drove around SoCal for the next several weeks accruing another 1000 miles or so. At 4,000 miles I was informed that Trans-Go had a new shift kit they were preparing for market and had it immediately installed.

What we found in the tranny was a little disturbing. The second gear clutches at only 4,000 miles were already starting to burn up. This I was told is the major weakness of the Allison 1000. The Trans-Go tranny kit modifies the second gear clutch springs and modifies the line pressure for all gears. The torque converter is sub par for the extra hp and towing that most of us do. So I choose to buy the Vigilante triple plated billet torque converter. The kit also stops the shuttering of the 4-5 shifts under a load by locking the converter up immediately instead of progressively.

I am told the new converter and tranny kit is good up to 900lb/tq. This is more than enough for me.

Technically specking the stock tranny is only good at the factory hp rating of 300. Anything above that and the weak areas like the second gear clutch pack goes south fast. Combine the extra hp of a programmer and a heavy tow load and it will go that much quicker.

The reason for this was shift quality. GM wanted a Cadillac shift in a HD truck. The tranny is good for 100,000 if Mom and Pop Jones use it to get groceries but not if you release the extra power from the DMax or tow with it.

The truck now shifts better than any of my Dmax/Allison trucks ever did before. I took a couple of picture of the box because I was late for the whole installation. For the complete price of the installation and parts I will refer you to Marvin. He is one of the master minds behind the kit.

I will be installing one of these very soon in my own truck and will post a detailed documentation of the install and my personal thoughts on the kit.

Eric; That would be great if you can do a write up on how it performs after the install. Also it is nice that you will be doing an install. Because that sounds like the one I may end up going with. In big part because of price, and becuase it sounds like it will handle everything I will ever throw at it.


Thanks in advance for the write up!

I am determind to attend. I am not cancelling my reservations at the hotel. I will find a way to be there. I have made plans to attend other get togethers in the past, and were not able to make it. This has to be different.
I will see you on the 10th and or 11th of October 2003.
