I was returning home from work...and the Lumina just didn't run! Near home it gave up! No shifting gears! It only parks! What do you guys think it is? I have another good tranny but no converter. Maybe I'll just swap to L67/4T65e-HD but I wanna do the swap with headers but I cannot aford them at the moment. Since I have been buying everything else for the swap...what do I do?

do you have another car?
if you do, you can just drive it, and start ripping apart the lumina

I'm assuming you've already checked the transmission fluid?

[stonecold0469]

i was checking and i saw that the oil didn't go down... i'm guessing is the oil pump...

huh?

He means did you check the fluid level, with the car warmed up running in park.

[stonecold0469]

Here's what I did: I check the fluid with the car off, had too many in it, then warmed it up, went throught the gears and check the fluid and it was at the same spot, when the oil pump is working it is supposed to go down After it warmed up and never did!!!

To check the fluid you HAVE to have the car engine running, car in park and the car on level ground. Otherwise there is no point in checking the fluid, whatever indication of where it is on the dipstick is useless.

Yes, the fluid needs to be checking with the car running and hot. I recommend checking it after you come home from work or something. That way its nice and hot and its been through all the gears. When you pull into your driveway, put it in park then slowly shift it through P R N D 2 1, then back up, leaving it in each gear for about 3 seconds. Then check the fluid. This will be the real level.

[stonecold0469]

Yes, I know all this stuff...but if it's cold and then I check it hot! And it doesn't show the "real level" it shows the cold level! Meaning what????????? Take a guess???

That made no sense at all to me.

[stonecold0469]

The idea of checking the fluid cold is that when it's hot, oil WILL go down..
.so you know that the oil pump is good, like you all said, it has to be done
running...why? So the oil pump can pump all oil into tranny, this is why I
checked it cold, if it has 3/4 of oil cold, it is supposed to have 1/2 of oil
after warm up, cause the oil pump is working...I don't know how to explain
this

That does not tell you if the oil pump is working, that doesn't make sense. You check it when its hot and running because that's just how you do it!? That's what the owner's manual says to do and that's what the dipstick is setup for. That's the only way to accurately read fluid level. Checking it when its cold then guessing how much it will go down doesn't work.

[stonecold0469]

I took it to a shop since I plan o rebuilding the old 3100 and it is the pump, the gearing of the pump they told me but since I'm in the middle of the L67 swap I'm not fixing it! For now!

[killaz1337]

Don't know where you heard that from. But it has to be FULL not 1/2 when warmed up in park, who gives a sh*t what it reads when cold.

Chris,

he is not saying it supposed to be half full. what he is trying to say is the reason that you check the fluid hot is because the trans has had time to pump fluid through out the valve body and whatnot. that is the purpose of checking your trans fluid warm because after you have been through the gears the pump has moved the fluid around during the changing of gears.

THANKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Sounds to me your suspicion that the pump gave out is correct by what you said. If the fluid level does not change from running to stopped then the pump cannot be running......

[stonecold0469]

see!!! and you thought me was crazy!!! LOL Thanks Again!
