Still learning the simple stuff... ... when did the ETC stop and the ETH start? Or perhaps the ETH designatesthe HO model?????



Thanks!

ETH is HO, for your year 2001 requires DEE which is the 6-speed with an auto you have the ETC

MCummings - I realize that all ETH's come w/ the DEE and that in the first few years the DEE was offerd w/ the ETC as an option before the ETH made its entrance; but here is my question-- Could you order a DEE with a ETC in 2001 and 2002 or was it only for the ETH's in those years ? TIA , Thomas

Well, I think you could get them only in the early 24V's, and it was a RARE option. My truck didn't come with a 6-speed, but the little 5-speed had too much of life behind a 450HP Cummins and trying to tug 25,000 pounds around. (input shaft shipped a tooth and she locked up tight)



Luckily for me, a rebuilt 6-speed was only a few hundred dollars more than a new 5-speed.



The difference between the 5-speed and 6-speed is amazing, there is actually a gear for almost any speed, and any load.



So, No, the 6-speed was only an option early in the 24V production, and now the 6-speed is only offered with High Output motors.



Hope this helps,
