how to know if transmissions in the junkyard is any good?
 

went to the shop today, and told that my transmission has problems
i can only go up to 40 kms/hr and i cannot go further.

any good tips on how to check for transmissions in the junkyard?
seen a couple of 5th gen maximas, vq35de engines, will it fit into my vq30de?

If the boneyard offers a warranty...get the warranty.

dont know if the 5th gen works, but the jy trans is a gamble. found this through a search. just an option...http://www.woodfins.com/Parts/1998-N...nsmission.html

thanks man! i was looking for online store that sells transmissions. but couldnt find any.

yeah ill check it out.

Are you sure its the trans? How high will the engine rev? might be in limp mode due to MAF or something.

:sprint:

FYI - LKQ parts usually come with a 30 day (or more) warranty.

Yeah that don't sound like a transmission issue man. Do you have any service engine lights? Plug in a code reader before you go invest in a tranny and waste your money. That ish will hurt. But my guess is the same as the last poster, MAF sensor is defective and your car is in safe mode preventing it from doing any further damage

he's lookin for a trans, not a new vq. i would def run codes and check maf

Opps. I didn't realize I typed engine instead of tranny :gapteeth:

yeah did it, and cleaned the EGR. and ill check that out too..

What is a MAF? sorry.. for being noob.

Attachment 40155

mass air flow

mass air flow sensor, its that round thingy behind your airbox and if its dirty the cars runs bad. ( technical terms, thingy and bad ) you have to spray some cleaner in there to open it back uo and get it running smoothly again. crc makes maf spray, use that. there's a write-up on how to do it in here somewhere, search is your friend. :cool: chrome, u suck. beat me to it.

thanks bro, and the other thing is my car keeps going on 40kms and hour and cannot go to 2nd gear.. its a auto btw..

might be in safe mode

here's a pic of the inside of the maf, you spray the little sensor in the middle. scroll down through this thread, you'll see. 10 minute job. http://forums.maxima.org/4th-generat...-your-maf.html there's a video too!

thanks broo! ill try cleaning it tmrw!

I've Had Good luck with JY Trannys....Got mine in my car now 5 months ago out a Smashed 97 with 85k miles its beautiful...try n find one with lowest miles and has been wrecked badly then u know its good,the maximas dont have transmission problems so 90 percent of them in their are still good unless its been raced or any performance parts on it...Good luck.

The tranny has a bad odor to it that's a bad tranny and a bad fluid stay away from it. the color is gonna have red or brown color with metal shavings .The tranny has to be token apart or atleast installed to really know if the tranny is good. The tranny with low miles can be goos but you won't know for sure tell the tranny has been installed, it could be in limp mode or it was abused ect.

or in an accident which is a 50/50 toss up if damaged

if it was in limp mode the auto tranny would just stay in third wouldnt it??? cuzz i hit a huge puddle one day and it went into limp mode and i was stuck in third till i restarted the car.

also if its in limp mode a mac truck could beat you 0-60 easy.

IIRC, its second gear with a 2500 RPM limit.

I was in limp m ode when I accidentally fried my tranny computer. After $190 diagnosis fee from Amcoo transmission and $35 tranny computer off eBay I was good to go.

thank you ill check that out in spring time, ( winter is here in canada)

it gets cold in us in november as well....:goofy:

I know technology has came a long way since but 10 years ago when i had my 90 accord, the tranny would not shift and thus keeping me from getting to a higher speed obviously. We were gonna buy a used trans from the junkyard until the guy told us these year accords have a common problem with the transmission solenoids going bad. There was a solenoid that controlled 1st and 2nd gear and a second solenoid controlling 3rd and 4th gear. We paid like $20 and the solenoid only took 2 bolts to put on, on the outside of the tranny. Cant say if these trannys have anything near the same thing. Only input i can offer sorry

sorry for posting on this thread but i have transmission trouble. i reacently changes the solenoid pack in my trans and ever since my car reverses, but doesnt drive on D only 1,2 recently it drives on Neutral and D but its not reversing it reaches 40 miles thats its limit. it revs to 7000 rpm could go higher any help would be much appreciated

sounds like you have to adjust the transmission shift cable.

could you post a how to or some thing plz

Aren't you the guy that accidentally cut the solenoid wire? Did you solder it like was suggested?

soldered it back same problem but the first time i did take the shifter cable off

the car stopped reversing i think i need a new trans. i found a couple of used ones in the junk yard. to keep cost down might atempt to do it myself

why can't you guys be local to me? I have a trans I need to sell, for super cheap. Good luck with your search though
