I am assuming you have the 200 4R, I just replaced my tranny fluid on my 87 GN, took about 6.4 quarts. I also have an external tranny cooler and let the tranny drain for about a week.

I would start with 4 quarts and start her up, dont drive anywhere. Keep adding and checking while the car warms up. Every now and then get in and shift through the gears, pausing in each one a few times, ALL GEARS. When the fluid level refisters on the dipstick, take the car around the block slowly at first then fast enough to shift into 2nd, depending on factors 3rd or 4th. Head home and leave engine running, check fluid again and adjust accordingly.

This is a common problem on some GM cars. There is a pressure control valve in the side cover of the transmission that needs to be replaced. The transmission does not have to be rebuilt. You will need to get a side cover gasket also.

What is the oil capacity level for a 454 big block motor

If it is a stock '85 Buick Regal (which I doubt), it would be about five quarts, but if the motor came out of a truck it could be six quarts. Look up the serial number and find out what you have.

1992 Buick regal 3.8 L has NO POWER TO 20 AMP FUEL PUMP/ECM FUSE AND FUEL PUMP RELAY UNDER THE HOOD.relay does click though when first turn on the key?? only fuse blown was the trunk release.I have swapped...

If the transmission was slipping, there is no fix for that

Being a 1992 i would talk him into parting with it

To old to be rebuilding a trans & you will need wiring
diagrams & most likely more knowledge than you have
to use them, for all the electrical issues

1989 Buick Regal Limited Oil in Engine?

It depends on how much oil and how long the engine ran if any.
If you put in 2 quarts too much but did not start the engine, no worries.
if you put in 2 quarts too much and drove it for 50 miles, you could have damaged some seals and they may start leaking. Odds are you did not damage anything internally.

1989 Buick Regal Limited Transmission Fluid?

I'm not sure I am following your problem.
A transmission holds 10-15 quarts including the torque converter. When you drain the fluid you are changing about 4 quarts of the full amount.
Once you fill the transmission to the full mark on the dipstick, you should not be adding more fluid unless there is a leak. Or if the vac modulator is damaged and allowing fluid to be pulled into the engine. The fluid is checked with the engine running in park.

What cause my 1995 buick regal to jerk at 55 just before passing gear,i do have a leak in front tranmission line would that be it

Stop any oil leaks as the transmission requires exacting oil pressure to do the job. Any leaks reduces the pressure so gear changing is affected. Besides when do you know if the oil level has dropped below operating level and will be insufficient for the gear box.
