highway RPM

[SuperHO]

assuming a straight, flat and smooth stretch of 4 lane divided highway without the AC cycling, what RPM should i be seeing in 4th at 75mph steady state cruising?

 

[lowc]

mine stays around 3800

 

[SuperHO]

if that's not a typo, you're doing it wrong...

 

[lowc]

i could very well be wrong i was just guessing where is yours at

 

[SuperHO]

it sits around 2800+/-, depending on incline. 3800 would be around110mph...

Mine is also at about 2800 rpm at that speed.

pax, smn

I'll have to check sometime. I have a failing TCC (for the last 5 years) and I know it has to be higher than 2800.

Just under 2800 is right with the converter locked in 4th gear.

Mine runs 2500 @ 65 mph on flat 55mph highway. I drove it civil to check my fuel mileage.
Added 1/26th 2500 @ 65 mph it did jump to 3k rpm then back to 2500 on a slight grade
going up on the Highway.

Mine runs 2500 @ 60-62 mph on flat 55mph highway. i drove it civil to check my fuel mileage

Somethings not right.

2500rpm in 4th gear with the converter locked should be 72mph.

it seems like depending on wind and inline i can run between 60 and 75 at no more then 2500 ive ran 70 at about 2200
