easy d series swap not so easy??
 

daaammmiit, i just wanted to say that because ive have been waiting for like 2 weeks to get a new motor cuz this kid blew his d16z6 and then we traded cars. so i have been out of a car not being able to go anywhere.

anyways, so friday i got my motor(jdm d15b)and we swapped it out today. well, after much turmoil the motor is bolted up to the ex trnasmission and in and fires up. so, my friends that know alot more about motors than me leave cuz they had to go after speniding all day at my house. they told me to put the transmission fluid in and it would be ready to go.
i put 2 quarts plus a lil more tranny fluid in and started her up. she is runnin good then the idle starts going from like 1500 to 2500 then back down and so on. im like ---- it so i pulled it out of the garage. i went up and down my street and then on the way back i shifted nto third and got nothing. just like someone else said in a thread. i pushed it into my garage and in any of the gears it just sits there, making a kind of grinding noise it sounds like, going no where. what could be wrong with this? as far as the idle revving up and down and my biggest concern the car being in gear but going nowhere??? p.s. could the idle problem come from the white sensor on the back of the intake mani being bad?

Vacuum leak and did you bleed the clutch

Re:easy d series swap not so easy??
 

vaccum leak, any ideas where? and, bled the clutch at least to the point where it is kind of stiff. i didnt really know how to do it and i had my lil bro help.

Re:easy d series swap not so easy??
 

i would say your trans problem is either the clutch isnt bled good enough, theres not enough oil in the tranny ( you did put 10-30 in it and not atf correct) or your tranny is fucked and the idle surge is either a vaccum line leak on the intake manifold, intake manifold gasket leak, or your IAC on the back of the intake is fucked, good luck....

Re:easy d series swap not so easy??
 

it is your axle that popped out of the tranny.
the grinding noise is created by ur loosen axle grinding against the Unlimited slip diff. :P :D
check the tooth on the axle, if u hear grinding, it`s prob.ly gone already. $$$ :-\

Re:easy d series swap not so easy??
 

im about to go out outside and check out the axle, and i put 2 quarts of honda manual transmission fluid in it. and as for the idle problem, which one is the iac? is it the white sensor on the back of the intake mani or the bigger black thing on the back. o, and from the z6 intake mani to this one, this new d15b doesnt have the evap purge control valve(i think thats what it was)

Re:easy d series swap not so easy??
 

shouldn't matter, evap perge crap is for smog ----. u needa go all around your manifold and look for any open vaccume sources. plug anything ur not using and make sure there's NO holes anywhere. if that's not it then take off ur intake hose and put ur finger over the hole in ur throttle body. if it idle's down nice n calm them ur plug ---- on the back is screwed over.

Re:easy d series swap not so easy??
 

More than likely donald is right, it's happened to me before too. Check the axles and make sure they're in all the way (i like to tap em in with a hammer now just to be sure). But also check your clutch and make sure it's bled out too, could even be a combination of both things lol. While you're at it, check to make sure you bled all the air out of the cooling system, as air bubbles can make the idle raise and lower too.

Re:easy d series swap not so easy??
 

hole in the throttle body? we got the axle out and it looks ok, it definetly wasnt in all the way, but now we cant get it to go in all the way??

Re:easy d series swap not so easy??
 

maybe u messed the clutch up when u put it all back together!

Re:easy d series swap not so easy??
 

ok heres whats weird, it took some prying and strength to get the axle to finally come out. ok, the teeth on the axle look good still, but now it wont go in all the way. so that could be the clutch?? and, for the idle, i read something about bubbles in the coolant line. we took the cooling system out could this affect it? we turned that screw on the throttle body but it didnt change the idle problem at all. we have no idea what else it could be. and there is a cel, if we could just get the axle i could take it somewhere and have them check it. this pisses me offffff.

Re:easy d series swap not so easy??
 

The clutch will not prevent the axle from going in. Line up the splines and smack that thing in. Bash on the end with a rubber mallet until it goes in. So did all the fluid come back out when you took the axle out again? It should have, now you have fill up again.

Re:easy d series swap not so easy??
 

no, none fluid came out. but i did read somewhere that fluid doesnt come out on the drivers side when u remove the axle.

Re:easy d series swap not so easy??
 

the axle won`t just "pop" in because of the metal clip.
if you can`t get it in
put a zip tie around the clip. push the axle in to the tranny until the zip tie is being pushed backward. cut the zip tie and hammer it.
as of the idle problem.
make sure u bleed the coolent right
reset ecu
make sure theres no vaccum leak
make sure TB cable is not over tighten.
make sure the TB plate is clean so it doesn`t leak
make sure all the ground wires are on
adjust idel screw
if it still doesn`t work.. i`d try to adjust the bolt inside the cold idea valve loacted underneth the TB, whenever it came loose it will idea like ----, but if it is too tight the car won`t rev high enough on cold start and it could stall.

Re:easy d series swap not so easy??
 

thats not right, i just got back to my pad from swapping my trans in my EF, if you have the right amount of fluid in it it will drool out of the axle input, it should take about 2.5 quarts. when you add fluid to the fill hole fill it til it starts to run out a lil let it dribble until it slows then plug it.

as far as your axle not going in just put the axle nut over the threads almost to where its level but not, then hit it in with a dead blow or sledge hammer, boom its in make sure its straight when its in.

from what it sounds like how you have nothing it sounds like your pressure plate wasnt tightened down all the way, no pressure no clutch, no move. :) good luck buddy.

Re:easy d series swap not so easy??
 

the white plug on the back of the d15b is your iat sensor, if you're cel isn't on for it, then it's fine, and yes, the axles don't just slide right in, you have to hit them pretty good sometimes. you'll get it, this is just part of swapping an engine.

Re:easy d series swap not so easy??
 

ok well, im gonna mess with today all day if i have to. i hate working on it though because it is like 15 degrees outside and our garage doesnt have a heater in it.

Re:easy d series swap not so easy??
 

holler! yup, we got the axle back in and as for the bad idle i was having, we put coolant in the radiator and it stopped instantly. so the car is driving and idling good, but i still have a cel. buut. there is still the grinding noise coming from the transmission. it makes the sound when in gear and in neutral, but goes away when i push the clutch in? does anyone know what that could be?? i was thinking since i have a new clutch to go ahead and put that in, would it solve the problem?? and, what is the process of changing the clutch on this motor besides having to take the motor all the way out or is that the only way??

Re:easy d series swap not so easy??
 

You had a new clutch but didnt install it when the motor was out bad choice. You have to drop the trans just has much work has pullin a motor in my opinion

Re:easy d series swap not so easy??
 

no, the clutch just came in, we would have put it in if it was here.

Re:easy d series swap not so easy??
 

yikes, i would have waited for it to come in, now you have to do it all over again :P
