We used to bump start auto's back in the old days. when we had sub zero temps a lot of cars would not start due to weaker batteries and starters that needed more power than current ones. we used a tow rope or chain and had to get going about 40mph before the engine would start spinning.
I would think that would be pretty hard on the tranny though.
On old automatic transmissions they had a pump working both ways, so that you COULD bump start them like you said. Since the 80's though, I dont' think any automatic transmissions have this feature
Just started doing it! Finding more and more opportunities as well. I would like an engine kill and engine start button though. Diamondlarry just pm'd me how to put in an injector kill, I'll get that hooked up ASAP!
Wow! there are some really exceptionally good gas mileage auto's on here! I'm hoping my gas mileage will go up soon, I'ts hard to get around to working on it with so much else going on (graduation next friday woot woot)
Another auto CRX here. I've hit 42 mpg on long highway trips, cruising at around 75 mph. I generally get 34-37 in day to day driving. This is with a D16Z6 swap (done for power rather than FE) and the lockup solenoid wired to ignition switched power.
The Scion xB has an automatic and I'm using engine-off coasting daily during my commutes. I just got a ScanGauge II about a week ago and have begun to watch the instantaneous MPG and tank average. Today I managed to attain 40.3 mpg overall for my 26 mile roundtrip. That feels like progress.
