High Performance: Performance Diesel Engines and Fuel Efficient
Transmissions; those of you who have spoken to me on the telephone or at truck shows know I an NOT a fan of the 10 speed transmission, my preference is the 13 and 18 speed transmission. The very first loaded semi I ever drove was from Pittsburgh, Pa. to Green Bay, WI. and the truck was equipped with a 15 speed Eaton Transmission. Years ago I thought that a 15 speed was similar to a 13 speed just with 2 more gears, man was I wrong. Talk about learning the hard expensive way, after driving that truck even on the level terrain to Wisconsin my desire to keep the engine at a given RPM was hampered by the fact that you can’t split a gear in a 15 speed. The 15 speed is a 10 speed with 5 lower gears that were never used in most operations. The RPM of the engine with the 15 speed trans was either too low or too high when driving with traffic. When there was no traffic and I could determine the speed, the 15 speed was livable.
My feeling is when you’re driving in traffic, 2 lane roads, construction, cities, towns or mountains, you have more control of the RPM of the engine when you can split the transmission such as the 13 and 18 speed transmission. Fleets tell me their drivers are not smart enough to drive the 13 and 18 speed transmissions, so they stay with the 10 speed. I’m shocked at that statement, if their drivers can’t back off the throttle and move the button on the shifter to split a gear, why are they even driving a semi truck.
Now here is the problem with trying to trade in a 10 speed on a 13 or 18 speed transmission; the demand for the 13 and 18’s are very high due to the amount of glider kits being built. There is a shortage of 13 and 18 speed cores so you will have to pay a core charge to make the exchange.
We have Eaton 13 and 18 speed Reman and brand new transmissions. If you’re interested in having a Micro-Blue Transmission, we will have that in stock also. The Micro-Blue process usually allows the truck to gain ½ mpg of fuel savings. The cost is an additional $2500 for the Micro-Bluing.
Another new product available is the VG turbo for the DD5 EGR Detroit, this is a brand new replacement, not a rebuild, and the price is $2400.00 The factory needs cores to replenish their core bank so we will need your old core in exchange. I think you will find this price is about $600 lower than the price of a Detroit exchange.
The 6NZ Caterpillar, one of the best and most sought after diesel engines in the world and the #1 engine used by owner-operator for glider kits. We just finished building a Signature Series Pittsburgh Power 6NZ Cat and it’s available to you. Horsepower will be adjusted to your specific needs. This engine has been lined bored, block resurfaced, crankshaft polished, magnafluxed and straightened, liner protrusion set to our specifications so there will NOT be any head gasket failures, all new genuine Caterpillar parts, ported and ceramic coated exhaust manifold, high performance Cat Turbo, crankshaft damper, mercury filled engine balancer, new oil pump and water pump, and custom ECM programming. The rods and pistons have been balanced. If there were a better way to build an engine, we would do it!
