Why am i getting transmission fluid in the big black hose with circles on it where the gas should be coming through? At first it was coming through the coolant holder so i had a new radiator put on now this. And how much is this going to cost? I am having to add unsually fluid and looses power,and smokes when i start up or take off
how do I get it fixed
knocking goes away upon warmup. Air Conditioning not working.0 135k miles bought used, needed oil change, thick. changed it. otherwise seems to run well.)
Newer radiator,just had leaks repaired @ throttle body cooling circuit a month ago. Yest the low coolant sensor blew out of radiator body. What holds that sensor in? 96 lumina van 3.4L
ran out of gas now car runs like its running out of gas always but it idles fine
My GM 3.1L V6 has 4T60E auto transmission, which got about 85K miles on it. It has 1-2 band applied during overdrive range 1st gear, what does this 1-2 band do for 1st gear?

Note: 3-4 gear, no band applied. Thanks!
the theft loc is not engaged from what I can tell, it's not asking for a code, the stations tune and display, clock functions and it appears the head unit works as it should in all aspects but I can not get any sound across any of the speakers at all. One day while switching the ignition off from run I got static across the speakers for a fraction of a second. Can it be a faulty ignition switch causing all the problems? The car starts and runs fine.
98 Chevy Lumina V-6. I found the brake master Cylinder almost empty. Filled it up but have seen drops around the back firewall/middle of car some type of fluid recently. Just multiple drops. Some of it trans fluid I think. I don't see any wetness between the master and the booster. I haven't checked the wheel cylinders yet. Is there a brake line that goes from one front brake to the other somewhere between the firewall and engine? Is there any brake fluid blocks, ABS, etc. located around there? Please advise. Thank you.
My GM Chevy Lumina-sedan 3.1L V6 has 4T60E auto transmission with a number of its solenoids.

What is the TCC PWM SOLENOID? Is it different from the shift solenoid A&B? and the transaxle converter clutch solenoid/relay? what should be their ohm resistances' values, from using digital volt. meter? Thank you for your advice!
AFTER DRIVEN HOME (15-20 MILES)FINE AND 2-HOUR BREAK, MY Lumina-sedan 3.1L V6 AUTO TRANSMISSION, 4T60-E, WOULD NOT ENGAGE/RUN IN DRIVE AND OVERDRIVE POSITIONS, BUT RUN IN REVERSE, 1&2 (FORWARD) POSITIONS!

THE TRAN. FLUID HAS BEEN RECENTLY REPLACED, AT OK LEVEL, AND IN GOOD CONDITION (REDDISH COLOR). THE NEUTRAL SAFETY/START SWITCH ON TRANSMISSION BODY, HAS BEEN INTERMITTENLY MALFUNCTIONING, SO IT IS BY PASSED FOR THE ENGINE IGNITION. YOUR ADVICE WILL BE APPRECIATED1, THANKS.
Recently while idleing at stop after travelling for some distances, my 3.1L V6 Chevy engine stumbled or stalled, but did not quit or die. There was also metallic clicking noises during stalling!

The engine OBD I scanner showed trouble codes 37 (TCC brake switch stuck "ON") and 82 (3X crankshaft position sensor signal error). Since the clicking noise sounded like EGR's solenoid clicking, and engine stumbled or stalled, can any of these codes cause the EGR's solinoid clicking and intermitten opened?

Thanks for your advice!
My chevy 3.1L V6 95 engine recently has high-idle RPM ( about 1500), which last unusually long time, after the engine got first started in the morning after an over-night park. After that, the idling RPM seems fine.

Prior to this, the first start-up idle RPM sometimes fast settled to normal RPM, but sometimes slower. The IAC valve's terminal resistances has been checked okay according to a specification. And the morning temperature has not varied much! Your feedback is appreciated!
My chevy lumina 95 3.1L V6 has its alternator's charging output varies between 13V. to 14V. during a day of normal driving. Is it okay or not?

Note: The alternator's cables are all checked fine.
Thank you in advance!
so when im driving the car it drives good but when i get to a stop light or stop sign the car sputters and the car sounds like it wants to shut off. the rpms bounce at 500 and some time drops to 400 when at a stop.
and when the the rpm gauge drops the dash lights dim a little.
i replaced the IAC sensor, cleaned the throttle body, did a idle reset, put some injector cleaner in, and problem is still there. if anyone has any ideas PLEASE HELP
MY 1995 LUMINA-SEDAN 3.1l v6 engine at idling, recently starts to intermittenly stall with metalic clicking noise from the front of the engine around power steering pump, water pump or so. I have not been able to pinpoint it yet.
The noise sounds almost like solenoid clicking, but louder.
After the noise stops, the engine's RPM slightly moves up (like when the A/C compressor turn off). No error codes show up from OBD scanning. Also, this may be related: while driving at constant steady accelerator about 2000RPM, the engine RPM intermittenly surged and dropped, out of control.

The water pump is about 8 month new, but the power steering pump has about 130K miles or more, of usage; and the engine is rebuilt with about 8 month of driving.
Thank you for your assistance in advance!
