Automatic Transmission Question

Okay then I am an expert on this matter . Good and bad . The clutch is used just for stopping going and works like a manual shift . Autoshift actually floats gears . It is okay if you do not like shifting but comes with some draw backs . Driving down highway is good as long as you do not need to drop a gear to pass someone . Up hills not so good . Taking off in heavy traffic where you need to get on going like across a busy 4 lane divided highway , bad . Now you have different kinds . Freightliner I drove only had push buttons on dash . very hard to work and drive at same time . Only manual shift from 1 - 2 - 3 and stuck in what ever gear you chose . BAD. especially in an end dump going through mud fields and stuff like that . When it tries to shift the wheels stop turning due to being in deep dirt, sand , mud , up a hill , what ever and then your stuck in neutral . Kenworth I drove last 4 years had a different setup . It would shift all 10 or you could put it in manual and shift all 10 your self or in low for just first . Basically shifted like a manual but very slow . No quick shifting like 1 2 3 4 across the highway . manual is really for going up and down hills . These things are a failed technology . Lots of sensors and solenoids and other electronics that fail a lot . All our trucks were in the shop a lot getting them transmissions worked on .

Anyone driving a prostar with the Allison tc10? Is there a way to know which transmission is in the truck by the vin number? Thanks.

The transmission in my kw is an Eaton advantage 10 speed. From what I have read is its basically a 10 speed that uses a or to shift the hears rather then you doing it via a stick. It will even skip gears if you are light enough. The computer that controls it in mine is still learning. For instance it wanted to always start in 2nd from a stop I manually put it in 3rd at a stop twice when bobtail now it starts in 3rd when bobtail.

Personally I think the autos are a joke! I was in the same model and spec Volvo with the 12 speed ishift and now in a 13 speed eaton. They are the same year same engine same model just different transmission. The auto was a pain on slippery roads and muddy terrain. Could not control the clutch and when it shifted in the lower gears it spun or got stuck. Not to mention I'm getting better fuel economy with the manual at higher speed same rpm to mph.

Remember, Nathan, trucking companies won't spring for auto-shift transmissions unless they see a better bottom line and equal or better safety for people and equipment. So auto-shift isn't a joke.

Did you know an auto-shift has a manual option? Read the instructions, or look harder at the shift paddle. Hint for slippery conditions: manually select a gear one step higher than you think. The reduced engine power at the wheels will help reduce slipping.

C'mon now.... reading the instructions first? A truck driver? Just kidding & throwing a first post out. Long time lurker. I tried an automatic years ago - hated it. Have one now & my 51 yr old 3xreplaced left knee LOVES it!

omg that's horrifying! I would pray for you but it sounds like you've already been through h*ll and survived it, so you don't need prayers. I don't know what you need, but more surgeries is not it!

Man, bless your heart. You must have a ton of points on your 'Frequent Doctor Visitor' card. You must have at least a free ice cream or something coming by now.

My company blocked the manual mode and the power mode. We are restricted to the economy mode only.
