Got ready to take off in my car today for the first test drive, got in and went to put it in gear and got nothing, no matter where the shifter is, I checked the fluid and its full, got the rear off the ground and tried then and still nothing. I even moved the shifter by hand down there and it won't do anything, the torque converter is moving with the flexplate, I cut the wires going to he trans because I pulled the computer and harness. Help please

Unless a 700-R4 has been modified for a non-lockup build, it will overheat with a never-locking converter and not last very long.

Also known as: based on username, stick to cutting yourself instead of your car.

I'm curious though, what did you mean by the first test drive? first after what? but yeah sounds to me like you cooked something in the trans.

89rs454

Did you test start the new engine swap with no tranny fluid? That will do it unless your linkage is messed up. If none of the above the transmission is toast.

first drive after my motor and trans swap, I went from a v6 to my v8 and went to take the first drive

trans wasn't dry. But didn't have the correct Mmount of fluid in it, after I brought it home, I checked the stick and it had fluid in it. Started the motor and put the car in gear and it grinded. Walked up front with the motor running and checked my dipstick and it was dry. Walked over and killed the car, refilled the next day with fluid, put a quart and a half in, started it, let it warm up alittle and filled till it was in the checkered on the stick"full mark". Proceeded to go try to drive it and had nothing

fervernt

ok, and where did the trans come from? new, or used? if used, did you know for a fact that it worked? Did you rebuild the trans, and perhaps did something wrong? Not saying you did, just trying to get all the details.

I'm going to Ignore the last statement for the simple fact that you don't know me, but next time why not try being alittle nicer to leople asking for help? And don't judge by usernames to the person, I picked mine out 4 years ago for Xbox live because it was unique and no one else would think about it. If you met me you would know I was the complete opposite from my user name.

trans was bought from a friend, he pulled the trans and motor from an 89 iroc. Sold the motor and put the trans on the back self till I bought it. It was rebuilt in 03, still had the stickers on the trans but no paperwork. Car ran and shifted fine before the trans was pulled

89rs454

He was just asking? Have you been drinking tonight son?

fervernt

He was just messing around bud, chill. And he is right about the lockup stuff. When you get this all figured out with the trans not going into gear, you DEFINITELY need to look into getting a lockup kit in ASAP. without that you will destroy a trans quickly.

fervernt

How long was the trans sitting before you bought it? If it didn't have fluid in it, at least enough to keep the valve body lubricated, you're just asking for trouble if it sat too long.

id say 3 years, it had enough to read on the stick so it had oil in it atlest, but when i checked it with the motor going and everything the stick was dry.

89rs454

Well there you go.

evilemokid94

iTrader: (6)

explain?

89rs454

Well if it's dry when you start it's snapping some **** up. No one likes dry *****.

could it be possible the torque converter doesnt have any fluid in it? i was reading some archives on here from the past and saw where a guy had a leak with his trans, and the torque converter leaked down and when he went to move the car it wouldnt go because the converter was low. im going to see if the pumps working tomorrow, if it is im going to check the torque converters level.

89rs454

No, even the torque converter didn't have fluid it would still move the car, then clang around in the aftermath.

so am I looking at a rebuild, a new pump, what?

89rs454

Can't tell you that man. I can tell you to look it to it, this site is full of information

thank you.

I'd read through the attached link paying particular attention to Page 7. It's the only source of pressure testing info I could find doing a quick search online that I would trust. However, I would look to your FSM as the primary source for pressure testing and it wouldn't hurt to read through the procedure there as well.

http://bmracing.com/wp-bnmcont/uploads/117101.pdf

I'd confirm you have line pressure before you do anything else. I'd just hook up the gauge and run it for a few seconds just to confirm there's pressure. Also, make sure your TV cable is properly adjusted.

Br careful around hydraulic fluids under pressure and keep your hands away from the gauge, hose and fittings. You do not want hydraulic fluid penetrating your body parts.

You check the trans oil with the engine running. If you check it with the engine off, you're not seeing the proper level.

I bet the pump is broken

talked to my shop teacher today since he used to rebuild transmissions, he said it sounds like my trans isnt pumping fluid or very little fluid, he said there are several causes, kinked lines, filter fell off in the pan or wasnt installed correctly or at all, pump is gummed up or bad, or the torque converter isnt ingauged in the pump making it spin the pump and moving the fluid. any of these sound reasonable? im going to see if my trans is pumping at all, if its not im going to drop the pan, check on the filter and for metal shavings, if that all checks out, im going to check the torque converter and make sure its set then change the pump. but i was talking to my dad and he said that if the torque converter wasnt seated in the pump it would be too far forward and push against the flexplate

paulo57509

You might be able to crack the cooler line to see if fluid is circulating. You'll need to crack the line that routes fluid to the radiator, not the return line. IIRC, the "to" line is the one towards the top of the radiator.

evilemokid94

well cracked a line on my trans today and it is pumping, VERY well i might say, i had the return line at the top and i had tranny fluid shooting out of my radaitor while just cranking, not even running. my dad called his cousin who works on alot of chevys and he asked me if i had my wiring harness going to the transmission hooked up, i told him i didnt and he said that was my problem and i needed to connect it as there is a seloniod in the trans that alots the fluid to flow through the trans thus giving me my gears and everything. i hooked it up tonight and did a few other things and cleaned up my grage floor of all the transmission fluid and am going to try it tomorrow to see if it helps any... im at a lose here.

antoine

The plug is just for torque converter lockup,trans still should work with it unplugged

FireDemonSiC

I really hate to tell you this but you need to stop listening to your dad's cousin because he has no idea what he's talking about.

The wiring harness on the side of a 700R4 controls the TCC lockup ONLY. You can drive around with it unplugged all day and night you just won't have any lock-up.

Check your PM's. I might possibly have the answer to your problem.

FireDemonSiC

Sorry but this is physically impossible. The torque converter is a fluid coupling and spins the turbine by the force of the fluid exiting the pump. Without any fluid, you might as well have the car in neutral.

i pulled the pan tonight and i didnt see any metal shavings or anything floating around in it, well found a few brownish looking flakes but not many, the bottom of the pan had alot of clutch material on it, the black gunky stuff. i moved the lever on the side of the trans and it moved the plunger type thing on the inside of the transmission through all the gears, im lost now, the pump is pumping, the gear indecatior is moving smoothly inside, what else could it be? i could see EVERY gear going out on this thing, and not have metal floating around or any sign of being destroyed. could a clogged filter do this? even though its pumping fluid clearly through the lines? any suggestions at all?

evilemokid94

iTrader: (6)

Okay I'm lost, everything looks fine l. No metal shavings, no burnt fluid, fluids pumping, filter looks clean, fluids clean. Help?

FireDemonSiC

The problem is somewhere in the valvebody. Try getting ahold of Dana.

paulo57509

Beat me to it. After looking through the FSM I started to think it's in the valve body too. Go here, register and post your problem:

http://www.700r4l60e.com/forum/

Dana used to frequent this site; his Forum was hacked a few years ago and I'm glad it's back.

It would help if you knew what year model your trans is and the trans model itself. This link should help:

first off

you can let a tranny sit for years..if it was working when put away, it will work. when ya need it. dry or full..

2nd thing did you make sure your coverter was in all the way. this is the #1 mistake made by the do it your self guys.

and is not good for a tranny on start up.

Update, after calling several people about rebuilding mine and figuring out what is wrong with mine I finally just broke down and decided to get a rebuilt trans. I'm going tomorrow to get it. Although I might hang on to this one and see if I can fix it for cheap and resell it or donate to my shop class as a project transmission

I got my trans rebuild. And when guy put it in. It wont go in any gear. It will go in first but not like its suppose to. Can feel any bumps when you put it in re,neu,or drive. But when I hit the gas it get real loud and goes slow but won't shift either. Please help.

antoine

Alot of times when people install transmissions they don't seat the torque converter and theybreak the pump

I think something is stuck open in your valve body. You can call your local Tran shop and ask them tho. call as many shops as you can. I dont care if the clutches are fried and the bands are junk. it should do something especially if it is pumping oil. I cant believe how people respond to a guy asking for help. no one is perfect. Good luck guy!
