SOUND LIKETRANSMISSION OIL COOLER IN THE RADIATOR LEAKING WATER OR COOLANT INTO TRANSMISSION.IN THIS CASE IF TRANSMISSION FLUID LOOK PINK AND FEEL MILKY.IF FLUID RED WITH A LOT OF WHITE AIR BUBBLES YOU HAVE TOO MUCH TRANSMISSION FLUID IN TRANSMISSION.

    ENGINE OIL TURN WHITE.YOU HAVE BLOWN HEAD GASKET. WHEN YOU HAVE HEAD GASKET LEAK ENGINE LOSES COMPRESSION AND COOLANT LEAKS IN OIL CRANKCASE.

    What do i gotta do if coolant is in the tranny.

  • Jonah Oneal Mar 19, 2011

    FIX THE RADIATOR BY REPLACING IT THATS WHERE COOLANT ENTERING THE TRANSMISSION. I HATE TO TELL YOU.BUT IT MIGHT NOT HELP.YOU HAVE TO FLUSH OUT THE ENTIRE TRANSMISSION. FLUSHING MAY NOT HELP BECAUSE THE ETHYLENE GLYCOL IN THE ANTIFREEZE WILL BREAK DOWN BONDING MATERIAL IN THE BANDS AND CLUTCH DISC,CAUSING FRICTION MATERIAL TO TEAR APART.THIS WILL CAUSE TRANSMISSION FAILURE.YOU HAVE TO REBUILD TRANSMISSION AGAIN.IF YOU DID YOUR OWN OVER HAUL.REPLACE THE BANDS AND ALL THE CLUTCH PACKS FRICTION PLATES IN THE FORWARD CLUTCH HOUSING , DIRECT CLUTCH HOUSING, AND THE REVERSE INPUT CLUTCH HOUSING. IF YOU REBUILT TRANSMISSION YOUR SELF.WONT COST AS MUCH.FOR BANDS AND DRIVE CLUTCHES FRICTION PLATES.YOU CAN BUY MINOR OVER HAUL KIT FOR ABOUT $200.00 TO $300.00

That would be coolant from the radiator
trans cooler

Now you have to rebuild it again

    i meant the engine oil turns white

  • Anonymous Mar 19, 2011

    So you have both, a trans that has to come back out
    and a motor with coolant in the oil ?

    I think you may want to just donate it to the veterans,
    as I just did with an 18 year old dakota
    23 years is time to put it to sleep

    I cant do that, its way to nice and i gotta use it.

  • Anonymous Mar 19, 2011

    You will need at least 5 or 6 thousand for an engine,
    trans and radiator
    May as well do a gound up resto

I have a 1988 GMC Sierra. I replaced the transmission filter and gasket yesterday and now it wont shift out of first gear. Once it got to second gear but not third. I checked the fluids and they are all...


Did you put the correct fluid type in? Check to make sure that you didn't bump any wire connections at the transmission. Check to make sure that the shift linkage is hooked up correctly. Did you make sure that the filters were exactly the same? Some transmissions will have a deep and shallow pan option. Did you get the filter installed correctly. Your question lists two years in it. If it's a 1988 it is possible I think that it may still have a vacuum modulator on it which could be messed up or the vacuum line disconnected.

1992 GMC Sierra Reverse won't work. Reves but doesn't move. Other gears seem fine.


Either the linkage is worn for shifting, or the reverse solenoid is bad.
In which case, the transmission will have to be rebuilt to get at the valve body to repair.
Maybe try a transmission flush for about $100 before going for the rebuild which will cost 10x or more for.

Or, try a used transmission that fits your vehicle that has less miles on it.

1988 GMC Sierra shifts strange when cold normal when warm


You always add transmission fluid while the car is at running temps because transmission fluid expands when it's hot.
