What car caN i yank out the transmisssion for my
You need to know 2 things, how many wires go to your neutral safety switch and the length of your transmission. The switch is on the driver's side about halfway across the driver's door. Tail shaft length's differ depending on what GM put the transmission in. They cannot be changed without taking the whole transmission apart. You will have to change driveshafts.
Once you know those 2 things any mid or Full sized GM, includung trucks should have a trans that you can swap, although I would try to stay as close to 92 as you can. Hope this helps.
To much trans mission fluid
Drain it by disconnecting one of the transmission cooler lines at the radiator, putting something under it to catch the fluid and starting the engine; it will pump itself out; don't run it too long or it will pump itself dry! Then reconnect the cooling line and check the fluid level.
How many Quarts ATF wo/converter
4L60 transmissionService change only - 5 quarts.
Total refill - 11 quarts.
Because you actually are mixing the 5 new with 6 quarts of the old, if your fluid is old you might want to change it and then drive a few minutes and change it again to get more new fluid mixed in. You can get a total flush at an oil change store. (for a price).
Sir i have a leak
There are a couple of tests to get to the bottom of this issue, pressure test the cooling system, first. This should show the issue, look around with lots of light and a mirror....
Where is the air filter located on a 1992 buick
The air filter is a long rectangular shape and is located is the front section of the air intake cover. Dead center and right on top of your engine. It is square rather than round like most but still sits right on top of your carburator/fuel injector. 2 wing nuts release it.
Turn on ac to auto
Mine did the same thing. Diconnect the Positive battery cable. Leave it off for about 5 minutes. Reconnect and your system will reset itself. Get in and watch the numbers cycle. Don't start your car until the cycle is complete. If it resets but reverts bach to the "econ" thing then you need to charge your system (Freon).
Leaking water from block
It might be the coolant in your car, or it could be the window washing fluid. There is a lea for sure if there is water coming off of it. Just to be safe you want to take it in a get your hoses inspected for any holes that might be in them so that they can get it repair. Or if you have been able to locate the hose you can buy some sealant to cover the hole and you will not have to pay as much for getting someone to look at it.
I replace the fuel filter
I Would start by checking for a vacuum leak, these engines have problems with leaks around the intake you can try and spray a non cfc brake cleaner or carb cleaner around the intake and see if the idle speed changes if so the intake gaskets are probably leaking.
The ac wont come on
Open the hood of the car, start the car and turn on the AC, go and watch to see if the condenser kicks over and starts to spin. If it comes on, your AC needs recharged and inspected for leaks. If it never comes on, check the wiring, be sure the condenser has a belt.
My 1992 buick roadmaster cut
Could be your fuel pump has gone bad. You need to check your fuel pressure if it is below 5-10 lbs
you will have to replace the fuel pump..first check and make sure your fuse to the pump is good before you do anything..The fuel pump is located in the fuel tank and the only way to fix it is to drain your tank and drop it it get to the pump that is located on the top side of it, the cost of the pump should be about $30-50..shop around before you buy one...takes about 2-3 hours to do this..
