Let out transmission fluid, can i put it back and how

Buick has been developed sophisticated transmissions through years and it is critical that you add the exact type of transmission fluid stipulated by your owner's manual (typically in the back of the manual in a section titled Fluid Capacities.) When adding transmission fluid to your Rainier, be sure to add it slowly as the transmission fluid capacity is reached quickly and it is difficult to remove excess fluid if you overfill. You can add fluid through the dipstick tube! Hope this helps. May god bless!

This model was unfortunately not designed to have a transmission dipstick. In order to check the transmission fluid you will need to have your vehicle level on jack stands. It is advisable to have someone with a hydraulic lift or underground bay available to reduce injury. You will need to get underneath your vehicle and locate the transmission. With the engine running; cycle through each gear. With the engine warm there will be a check valve or fill plug. You will be able to remove the fill plug and if there is transmission fluid that comes out in a steady stream; the transmission fluid is not low. If transmission fluid doesn't drizzle out then you will need to have a fluid transfer hand pump available to put some transmission fluid back in. You should have a stream of fluid coming out when enough is put in. Good luck!

Should never re use any fluid alway use new fluid.

Don't run the engine at all. If it was started, the transmission pump will have pumped the motor oil all through the transmission-go have it professionally flushed. If the engine was not started, drop the transmission pan to drain the fluid, and get a new transmission filter. Put it back together and run the engine until the transmission fluid gets hot. Then change the fluid and filter again. After this, monitor the transmission fluid dipstick. If any traces of more motor oil in the pink fluid, do the drain and change filter a third time. (buy a case of transmission fluid-each drain and change will take about 6 quarts.)

if this is an automatic transmission, check your transmission fluid level. The fluid should be red, if it is orange/ brown colour and smells burnt. Will need to be changed. Take it somewhere to have fluid and filter changed. If you are mechanically inclined try flushing the fluid through the transmission. Disconnedt the driver side transmission cooling rubber line from bottom of rad. place the end of the hose in a large container. Put parking brake on, turn on vehicle and put into drive. the transmision fluid with pump out into container. Watch how fast it pumps out. When the fluids stops coming out, shut off engine and put back into park. Next drain remaining fluid out of transmission pan. There is 9/19 or 14mm bolt for this on bottom side of transmission. When this is done, refill transmission and repeat. This time you are flushing all the extra **** out of the transmission. Again check thre flow rate of the fluid coming out. It will come out faster this time. When finished replace transmission fluid again with new clean fluid. This should help free your shifting. When starting the engine for the first time. Put the brake on and put the shifter in 1st for a few seconds , then 2nd and drive, then reverse. This will also allow the fluid to begin to circulate.
If the transmission fluid was dark brown or black it would be wise to replace filter when you finish flushing transmission. To do this you have to disconnect the 4 wheel drive shaft to get pan off. Try just flushing the transmission first. I will look again in couple of days for your reply.

check it with car running pull ot transmission dip stick wipe off transmission fluid with rag put it back in all the way pull back out look on stick it tells you on there what level your fluid is at

1. check fluid while running in park or neutral
2. wipe stick off put back in check again look at both sides of stick
3. if need to add put fluid in tube where the stick goes
4. only add what you need check again

Before you put transmission fluid in, make sure it needs it. Check the transmission fluid with vehicle warm, engine running, emergency brake set and transmission in neutral. Pull the dipstick and wipe it off. Insert the dipstick back into the dipstick tube completely and then pull it back out. The fluid level should be between the two marks on the bottom of the dipstick. If it needs fluid pour the fluid into the dipstick tube (using a funnel). Only add about 1/2 quart of fluid at a time before you recheck it. Do not over fill the fluid.

first you need to buy transmission fluid new filter and new gasket.you need 11.4 pints of transmision fluid.raise front of vechicle.set parking brake.block both back wheels.besure support vechicle weight with jack stands. get a drain pan.if your transmission pan dont have a drain plug.loosen rear pan bolts a few turns.remove the front and side transmission pan bolts. let fluid drain.remove tranny pan. then clean old gasket material from transmission and pan carefully.dont scratch or damage surface.clean old tranny bolts using brake cleaner or buy new tranny bolts.you have to put a tiny film of rtv silicone on tranny bolts so they wont leak.carefully remove old tranny filter and put on new filter.clean all grease grim away from tranny pan it should be **** and span because.you might need a little gasket adhesive to hold gasket in place while putting pan back on transmission.to line up bolt holes.loosely put all bolts in you have to move pan a little to get holes line up.when all is finish put tranny fluid back in.besure you put 11.4 pints back in that about 6.5 quarts. make sure tranny fluid level is right before driving vechicle.l

NO, there is a transmission dipstick to check the level of transmission fluid, this is also where you would add transmission fluid if it is low.
