I have learned that the limiting was done to also extend the life of the transmission.

I own a 2002 Silverado LS Dually, 2WD. I purchased the Moroso wires and used NGK plugs and also use the Wix 51515XP oil filter since it is a 2WD. Switched to Mobil 1 Truck & SUV Synthetic oil and the oil consumption also dropped. With the larger oil filter, you have to add an additional quart of oil. If you truck is a 4x4, you cannot use the larger oil filter.

Try the Delvac Mobile 1 Allison fluid, it sheds heat better than any fluid we?ve seen.
If you can get an Allison trans I?d do that. If a fireman can?t break them they are bullet proof!

Barry,
Mine has the Allison 1000 series With my load and the "Tow" button on the shifter activated I have never seen the Trans temp gauge go high, even with the load of engine blocks. I'm assuming the trans temp should stay under the engine water temp. Water temp is never over 210. I really like the Transmission braking feature of the Allison. I think the up shift points are a little high, even when not in tow mode. I've been thinking about doing a Transmission & rearend service this winter. I have read up on the transmission and seems like they use a special fluid. I've been using AMSOil in my other trucks and was considering making a change. The truck had a Quaker State
Sticker on it with mileage for changes. I have used Q-state on all my changes. There is a little more oil consumption than I like...Thinking about making a change and see what happens.

Adger,
I had mine serviced and flushed recently and switched to the Transynd 668 fluid.
The shifting improved dramatically with smooth and firm shifts.

There?s a place in Perkasie Pa that might do it.
That is not far from Maple grove I think.
I?m not sure the would do a shipped in ecu though.

I used Rocket Chip on my 8.1L motorhome. Saw improved torque and throttle response. $99 and plus into the OBD port very simple.

Adger,
Yes, I do still have both. I also bought a 6 speed Allison, hopefully I can convert to that.


On your oil consumption, I have used Royal Purple in mine, the 20W50. Didn't hurt the fuel economy, and pretty much stopped the oil consumption. Excellent oil pressure at all times. The Transynd is the Allison fluid of choice.


The other problem for oil consumption is actually the horrible OE design for the PCV, it literally sucks oil right out of the lifter valley, the baffling is non existent. That's another common fix done during the intake modification.
