I have a newly rebuilt 22re with new clutch and assembly. When I start the truck in neutral my rpm is bogged down about 200 rpms and idles to low. When I engage the clutch in neutral it raises the rpm to normal operation at 750. Sorta stumped on it, any ideas? Clutch free play?

 

If it was me I definitely check your throw out bearing and clutch plates. It seems to me like something was adjusted too tight. Your friction pads are constantly making contact

 

It's the middle of december, the oil in your engine and transmission are cold and thick. When you have the clutch out you have all the gears in the transmission turning, as well as pressure in the motor on the thrust bearings. It's normal for it to idle lower to a certain degree. If it's THAT big of a difference then you may have a problem. Is the idle more consistent when everything is warmed up?

 

What oil r u running?

 

Engine I'm running Castrol gtx 5w30, tranny has 80w90. When truck is warmed up it still has the same rpm jump. The truck shifts runs great sounds great and I really don't notice much accept when I'm at idle. When the truck warms up fully its not really as noticeable as when I'm starting it at 5:30 am headin to work when it's like 28 degrees out.

 

It has something to do with your clutch. Something got torqued down too tight, or wasnt adjusted properly. Your tranny is maintaining too much friction between the gears. I know a yota isnt a "go kart" but think about a go kart clutch when its a tad tood tight, as soon as it warms up its got that 1/2 mph crawl to it... Id take it back to wherever you got your clutch from and let them know.

 

BTW, i dont know where you live, but ive personally read the dealership repair manual from JAPAN for our trucks. And it says for 10 degrees plus to use 20w-50 motor oil. I switched to it when i bought my current yota, and the difference is incredible! I have no valve tick and better compression, not to mention then engine just seems overall happer with it too. 20w-50 keep it synthetic.

 

first, i adjust all my 22r/ 22re's to idle at 900-1000rpm. they seem to like it there. all have still passed the aircare(smog) tests we have here .


the rpm drop is normal. with the clutch release( pedal up) even though you are in neutral, all the gears in the trans are still spinning. in the winter when its cold, it is more noticeable. have you even tried to pour 80w90 at freezing temps? its thick!!!! now try and imagine the work it takes for your engine to turn all that in the trans.

if it bothers you, you really have two options, run a thinner oil in the trans
or raise the idle a little

 

I had the same issue, but mine seems to normalize once things get warmed up. I am up in Canada and would love to start the struck and let it warm up without having to have my foot on the clutch so it doesn't stall out. Any suggestions?
