wut do you guys with the 3.0's turn for rpm's at say 50 mph. i usually get around 2 maybe a little higher, and i do know at around 70mph im pushing close to 3 grand.

i also have a little question, lately my truck has been acting weird. it is a 3.0 and when i mat it, it will pull good to 3 grand then for a second or so it will get hesitent, nothing to noticeable, but noticable enough to just start seeing it was happening.

then also, if i am in 2nd 3rd or o/d and i floor it the gear will drop ( like any normal automatic transmission does) and it will rev past 4 grand real quick then drop and get sluggish at 4 grand, it will go past 4 grand if im going down a slight downhill. any suggestions as to what it may be.

thanks for the help.

mines about at 1600 at 50mph, thats with 32in tires but the speedo is corrected (don't know if that makes a difference)

 

50mph I don't know offhand, about 1800. Cruising at 55mph I'm pulling 2000rpm and at 65 I'm doing 2300rpm... We SHOULD have about 1300 rpm at 55mph, but Ford decided to use the worst tranny in history...

 

ya....my 96 2wd goes at 1900 or so at 50 mph. what makes me mad with my truck is when im on the freeway going 65mph and i floor it, it drops into passing gear....so as soon as it hits passing gear it shoots to 5500 rpms and hitting the rev limiter.

 

interesting rpm numbers at speeds, hmmm..

any one have any input on what could be causing my truck to perform like that.


i appreciate it guys.

What year, how many miles, any previous problems, matinence... It's a good idea to have a sig with your truck's vital info so we don't have to ask

 

sorry guys. i tried making a signature, i typed it out, and saved it, and it never worked.

but the truck is a 1999 ford ranger 3.0 with about 115,000k on it.

 

changing the sparks plugs will probably help if you havent done that recently

 

very good suggestion nbro, i didnt think of that..

i appreciate all the help guys.

here the kicker question.......auto or stick??

 

 

around 1700-1800 id say, that is if it shifts, sometimes itll sit in 4th and not kick into OD until like 65, pisses me off

 

mine is about 1400,1500 max for 50 mph. at 70, it's ~2k (i have a bama tuner though...)

 

bama tuners dont change gear ratio's.. but your 32s do

 

yea it does... without the tune and 32's, it was still revving 3K for 80 mph, and 2K for 55 mph. Now, with tune + 32's, it's ~2500rpm for 80 mph and 1200-1300 rpm for 55.

i'm actually confused with your comment, haha. gear ratios? like.. rear-end gears in the differential? i know it doesn't change that, but i believe doug changes the shift points and rpm's, so that we get more performance and better gas saving (though i haven't seen it yet... the gas-saving-ness).
