Drain and refil gearbox oil on toyota conquest 1990

IF you have also changed the filter then add 4.5 litres of oil and check level after running engine for 20 seconds or so. Top up as needed.

Hi J, Clean the whole area around the drain plug and oil pan. Drain the fluid from the drain plug at the lowest point of the gearbox oil pan. When drained into the required receptacle, remove all bolts around the oil pan and drop it. The oil filter is located inside and held in place by fixing bolts. Remove those and replace the filter. This job requires the utmost cleanliness, and no contamination should be allowed to get inside the gearbox. Refit oil pan using a new gasket and refill gearbox to required level. Always check the gearbox level with the engine running, the selector in neutral and the park brake fully engaged. Regards John

Try with the small stuff first. Replace the thermostat. Before you do that, you should flush and refill your system with just water after the flush process. The bottle of solution that you put into your radiator to flush it and clean it has instructions, follow those. Then let the car cool down and drain the system and refill it with fresh water only. Run this water for a bit and then do it once more. Once cooled back down , replace thermostat and replace the 50/50 mix of antifreeze and water.
Check engine oil level as well, low oil will overheat engines quickly.

some trans dont have dip-stick tubes any more they are checked and topped off from under car when serviced also atf oil is very thin and has alot of detergents as compared to 90wt gear oil, i would drain and refill front diff. yes.

Make sure there is enough transmission oil in the gearbox, without oil the synchro's cannot work so gearchanges will be slow and cumbersome. If filling the gearbox oil dosent help maybe you have gearbox damage - have the gearbox checked out.

Take of the right or left side wheel and you will see a small dipstick for the diff

well there should be a drain plug might look a little flat on the bottom side of the tranny, thats were you drain the trans, to refill there should be a plug on the side of the tranny, your going to have to get creative on filling the trans until the oil starts to slowly trickle out . if you can get to the shifter and pull the shifter out and fill this spot

....

Nothing special but also replace the transmission-inner joint seal also and top up the transmission oil.

On the side of the trans. you'll find 2 bolts that have 1/2" drive holes in them. A 1/2" drive ratchet head will fit in. On the upper bolt, you'll remove it and this is the hole that the oil will go into. Use a pump that screws to the top of the oil container which is available at any parts store. Pump the oil into trans. until it comes out of the bottom of the hole. Screw the plug back in and tighten.
