How do you put get gear oil in the gearbox of a 1996 Peugeot 309 GL.?

I have a peugeot 309 on which i had repair work done on the axle a couple of days back. the guys who did the job are clueless about how to put the transmission oil back in the gearbox. Please help!!How do you put get gear oil in the gearbox of a 1996 Peugeot 309 GL.?
I have 3 cars with the TU engine and an XU5 engine, the 405 with a very similar gearbox. I believe your engine is the TU, XU or XU5, similar gearboxes.





NOTE! if you have an automatic gearbox, simply fill the gearbox through the dipstick pipe. If you have a manual gearbox, read on....





The gear box is on the left side of the 1996 TU, XU, or XU5 engine.


If you look over the top front edge of the left tire, you will see a filling hole BOLT. The bolt is removed with a square 8mm rod (just like the motor oil drain plug). And there will be a copper ring washer to replace, maybe a smaller size than the engine oil plug ring.


Fill the gear box with GEAR OIL. Fill it through that little hole, horizontally, which is difficult. I fill mine by using a little 100 ml, 5 ounce, squeeze bottle held in a level position while I squeeze. I refill the squeeze bottle 15 to 20 times. Or, create a funnel above with a long plastic hose into the gearbox filling hole.


Fill the gearbox until gear oil overflows the hole and runs out.





PS: did your friends find the drain hole, or did it all leak out upon removing the driveshaft (you said 'axle').








quoting from the WIKI pedia:


In 1991 Peugeot gradually phased in their all-new belt-driven TU overhead camshaft engines, a development of the XU series, in 1124 cc and 1360 cc forms, eventually replacing the Simca units during 1992.
