How to change the transmission oil in a Fiat Uno?

Model: Fiat Uno MK 1 - Years 1983-1995
Part: Transmission fluid

In this tutorial, we will see how to replace the transmission oil in a Fiat Uno, a very simple and quick operation. First of all, let's make sure that the engine is cool enough. Then, we open the hood, locate the fill hole bolt on the upper side of the transmission case, and unscrew it using a 12mm socket wrench. Next, we lift the vehicle, go underneath it, unscrew the drain hole bolt with an 8mm wrench, and let all the oil contained in the system drain out. At this point, all that’s left is to tighten the lower bolt, add the necessary amount of oil using a flexible hose, and also tighten the upper bolt.
