Max rpm for 1st and second gear on Auto V8

Evening,

As the title suggests, I'm just curious about the max rpm reached in 1st and second?
On my P6 (a second hand rebuild for a car stood for 30 years), it reaches about 4000 in first, and about 4800 in second before changing.
Cheers
Andy
 
At what sort of throttle opening? If that's with the throttle wide open then that's probably about right. If it's only on a light throttle but the changes still hang on to those sorts of rpm then the kickdown cable needs adjusting.

Sorry, yes, thats with the foot down to the floor.
Thats good to know, when I put the engine together I did it all by intuition, but noticed first changed slightly sooner than second.
 
Just to add to this, I've noticed since I bled the brakes (30 year old brake fluid required MANY brake compressions to get the gunk and air out...) the accelerator pedal is higher than the brake. Its a bit awkward as getting seat position right for both is a compromise.
Should they be at around equal height to each other?
 
The very bottom of the brake pedal should be 6.5" directly above the metal floor, so you can adjust that if it isn't, and providing you can still get full throttle you can adjust the throttle linkage to set the pedal into the most comfortable position.
I'd say in most cases the throttle pedal is lower than the brake, so that you have to come past the at rest position on the throttle pedal to get on to the brake, so there isn't the risk of having your foot operating both pedals at the same time.
