Do the DOHC models have a lower geared transmission than the SOHC models? Just seems like my girl's 97 2dr DOHC 5sp revs a bit high on the freeway at about 70 it's around 4k rpm. I'm just wondering if the SOHC is higher geared, maybe gain a few mpg?

 

the dohc's have a 5th gear that does rev higher for more get-up-and-go

 

spud the SOHC trans has a 3.55, the DOHC has a 3.94, plus 2 different 5th gears, depending on model

 

the sohc trans is geared a little higher for better gas milage.....
on the highway the dohc tranny will rev higher then a sohc.....almost 500 rpms higher...maybe a little more

 

SOHC runs good with a 5 spd from an r/t gas milege on the highway isnt all that great but its fun

 

my r/t with the 3.94 tranny averaged 38mpg on the way hope from virginia a couple weeks ago...and thats with a filthy stock air filter, and no tune up of any kind, and bad front tires...I bet I could have done 40-41 with a new K&N, plugs, wires, and good tires inflated properly!!!

 

the r/t tranny's arent bad on gas.....they just arent as good as the sohc tranny's

 

mine is, i think the way i drive has alot to do with it also

 

i was still getting 31mpg with my r/t tranny even when i was beating the hell out of it

now the car has the sohc tranny...but i dont expect to get better gas milage because of the turbo

 

dont worry after that turbo youll never see 30mpg again.
