Question about 1999 GMC Suburban

2 Answers

ATF is leaking out of the flywheel assy of my 99 Suburban 1500

99 Chevy Suburban with 62K miles started to leak out of the front of the torque converter housing. It drips all the time. I thought at first it was coolant leak but I checked all the hoses, water pump, hoses thermostat radiator and nothing. It drips out of the bottom front of the housing, some of the fluid is getting into the starter.
I am do it yourself, retired with a fix income and have some mechanical experience but I think this leak is to much for me. Could you tell me what I am up against and how much it could cost me.
Thank you

    I think you may be right; both ATF and the antifreeze are pink in color, that threw me off somewhat. I took some of the liquid to my local auto parts store and there the consensus is: coolant. My transmission levels are normal but every morning I check my coolant level and it is down. I have removed manifolds with carburators but not with fuel injection. What kind of tools I am going to need to do this job other than ratchets and sockets? and Is there a test I can do to verify that I have a leaky intake?
    thank you ralonso2411

If it is ATF then it is the trans pump or input shaft seal, these both require the removal of the transmission.

If it is coolant it may be a rear freeze plug, but this is rare and also requires the removal of the transmission

A more likley cause is a leaky intake manifold which is very common on the vortec v8 engines, it leaks at the very back and runs down the bell housing. this repair is a bit extensive but can be accomplished by a good DIYer given time, space and tools this repair is also the least expensive of the three, about $300

Torque converter stays locked when put in drive it slams into gear reverse not so much


Check for ATF leak first.
It can be on the high side of the pressure line.
Example
At radiator or along the line.

Check ATF after 5 minutes of warm up time.
=====
Check your service record for past filter/atf change.
The recommended interval is 24,0000 miles.

1997 Chevy Suburban 1500 flywheel broken


I just had to have one done after the first one was installed BACKWARDS by an idiot. To replace starter and flywheel cost me $890. IF you just need the flywheel you are looking at between $450-$600 unless you do it yourself.

Flywheel on 1997 Chevy Suburban 1500 broken


I would say about $200-400. It involves disconnecting the transmission and torque converter bolts to the flywheel (3 bolts) and moving the transmission back far enough to remove the flywheel.

99 silverado noise at higher rpm


You likely have a cracked flywheel. you cannot see the bolts without removing transmission so no one can tell if it's broken without taking it apart and looking at it. (If no cracks found between bolt holes, go ahead and do trans work, but I seriously doubt you will have to)
