Where do i put the transmission oil - 1987 Toyota Camry

Did you put ENGINE oil leak in the transmission? That's probably why the transmission locked up. If you put it in the engine, it had nothing to do with your transmission locking up. In either case, your vehicle needs to be diagnosed by a reputable, qualified transmission shop.

Your radiator needs to be replaced. Chances are you have transmission and oil cooler lines going through them and there are mixing inside the radiator.

NO JUST FILL GEARBOX LEVEL AND CHECK AGAIN AFTER RUNNING ENGINE

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.)

Use a funnel and put in the transmission oil through the transmission dipstick tube. Don't put too much. Insert transmission oil in increments just to be sure.

First Look under transmission for a drain plug like a Bolt size Then Open your Hood Check On the side for Oil gauge... From that Oil Gauge after draining your old Oil ...Put Back Your Bolt ..Then Find a little Funnel to put our new Oil throw that Oil Gauge.. Transmission Oil For Manual Transmission Only From Canadian Tire ...Good Luck

you can put it in the transmission dip stick tube with a small funnel

Your Catera has a sealed for life transmission so therefore on one of these models there is no dipstick and you cannot check the fluid level yourself. The dealer can check the level but that is only necessary if you have a leak. Use a premium grade oil and a quality filter such as AC/Delco, Wix, Purolator, or Bosch. The correct weight oil is listed in your owner's manual and possibly on the oil fill cap or dipstick.

I haven't changed the fluid in a Catera, but all the auto trans cars I have, it's added through the dip stick tube.

Improper fluids in a automatic transmission can cause severe results.
Drain the transmission fluid and change the filter.
If the car was running at the time you put engine oil in the transmission, I would also flush or drain the torque converter.
Replace with the proper amount and type of fluid.
