RE: auto trans shifts to early
On these old cars, the kickdown is not supposed to redline the engine like on newer vehicles.
It is merely supposed to shift it down one gear to make more power available to you on demand.
On ALL my cars including the diesel, when it kicks down, you feel the characteristic jolt as it activates and then the revs immidiately climb about 1,500 - 2,000 RPM's, the way they work is based on a car will accelerate quicker in a lower gear, no redlining like on the new cars does not mean it is not working right. All the switch is is a easy and automatic way of shifting the gear down on demand without moving it from "D" to a lower gear manually on the gear box - If it redlines on a kickdown, your transmission is probably slipping - these cars are not meant to perform like the contemporary cars, Mike, they are more relaxed and comfortable. Whereas, say my 1990 Audi V8 quattro will redline on kickdown, that's how is was designed.
A sign that your kickdown is not operating properly is when you kick it down and nothing happens, and you don't feel the jolt signifying the downshift.
Theses engines rev high for V8's, however, why do you think these transmissions live forever? Because it's hard to bag the crap out of them...
Hope this helps,
P.s-will get back to you soon about emissions etc...got some cool stuff...and the vacuum diagrams are mondo huge, would take hours of scanning, bro
