I don't because I D/L the digests only. I am on the road and get online only long enough to pick up email and D/L selected pages to be read off line. Saves big bucks when using an 800 # to call my ISP.

Same situation here. We use Sprint PCS to pick up and send email while on the road. Apart from being V E R Y S L O W it makes "chatting" very expensive and quite klunky.

Same here, we are on the road quite a bit and d/l everything. I do go into the chat room while home though but haven't had any success, I assume it was because I'm east coast.

Sorry about my reply to the pac brake, I thought it was about my continuing problem then I saw that another John had asked a question.
Interesting about the down shift though because I don't even get that so I manually downshift right now. JohnP

John,

My transmission also downshifts but no useful retardation occurs. When negotiating I70 over the Rockies recently, I downshifted right down to 2nd gear but as soon as the service brakes were released the engine RPM increase to red line in a few seconds and the service brakes have to be re-applied and kept on pretty much continuously. The closure of the PAC brake butterfly in conjunction with the downshifting is essential to provide useful retardation.

The reason for this of course is, unlike a regular gas engine that has a butterfly throttle on the inlet side and therefore operates as a huge vacuum pump when rolling down hill with the gas pedal up, there is no throttle in a diesel engine. It always ingests a full charge of air and its performance is controlled entirely by the quantity of fuel injected on each cycle. The engine thus operates as a massive air pump with no restriction on either the inlet or exhaust side. The PAC brake on the Cummins engine produces a back pressure of up to 60 psi when closed and this back pressure is what produces the braking effect.

It will be interesting to hear the Allison outcome.

Peter.
