ok guys got a prob i had for a while when im going around 70 on the freeway when i lift off the gas within 2 secs im at 60 almost 57
i have a 89 x cab about 3 inch lift 31's bfg with mild tread nothing crazy
i replaced new calipers made a lil diff and a new cat converter
i have the v6 3.0 get really bad gas milage from these

also i noticed my boot to my driveshaft was tore i got that ordered here tom doing it myself do you think wheel bearings? inner and outter i know there have not been inspector in over three years!! please help love this website big help on alot of problems thank you

 

auto or 5 speed? fuel filter, tranny service, spark plugs and timing check, air cleaner? condition of all there will help figure out the problem.

 

auto, eveything is good i dont know about timing how could i check that and i do have a small prob with my tranny only when its cold it doesnt like to go into the last gear on the freeway until like 5 mins on the freeway but then its fine the rest of the day

 

sounds like it might be a transmission problem. check and see what your fluid level is and see what color it is.

 

thats the thing fluid level is good and looks good
my uncle said maybe the pump in the tranny????? but i dont understand how that would cause drag on the freeway

 

if it is not pumping the fluid right it would cause it to not give all the power to the tranny and this in turn will make u need more gas to keep it going at that speed and when u let off drag and slow quick. mine was acting like this and i changed filter on tranny and fluid and it made a big difference.

now have u checked the bearings? lift it off the ground and turn wheels see if u have a lot of drag on one tire vs another,

 

im gunna go do that now and is the pump job prety hard my uncles knows how but can i do it at home or do i need a shop to do it i hate paying shop fee its a rip
also before u changed the pump did u have a problem with ur reverse? when i put it in reverse it goes but when i hit the gas real slighty. if i backing my truck up from the gutter on my street i cant even get on to the sidewalk unless i either get momentum or i lock in my 4wd locking hubs

 

sorry read that wrong the filter i done that before on my buddies truck i will do that tom and ill let u know what happens thanks man really saved me alot of time and money

 

i didnt have the problem with reverse. if u hit the gas in rev. does the motor rpms go up but the 4runner didnt move much? it could be a torch converter going bad too, but that usually affects all gears, the only thing i could think is your clutch plates are going bad and its time for a tranny rebuild, but i would do a tranny service and add tranns medic to see if that helps. but i will warn you that it could make it worse just fyi about it.

 

I had a similar problem Make sure none of your brakes are sticking, Torque converter should unlock when you let off of the gas, check and clean all the electrical connections to the trans. Hope this helps.

 

it was my trans filter runs alot better thank you all!
