In The Most Recent Video Of The Mega Dicas Automotivas Channel, The Host Shows Step By Step How Silicone Grease Can Replace Petroleum Jelly And Keep The Transmission Light, Firm And With Precise Engages For Much Longer.
The channel Mega Dicas Automotivas published a new version — called “2.0” — of a video about lubricating the transmission rod, providing a practical update for those facing the “sloppy” transmission issue.
The mechanic explains that this type of play is a result of the natural wear of the internal bushings, which lose efficiency when they do not receive the correct lubricant.
The purpose of the video is to show how silicone grease can solve the problem and keep the smoothness of gear shifts for much longer.

Solid Petroleum Jelly Melts And Loses Its Effect
The author recalls that, in the previous version of the video — published about four or five months ago —, he had used industrial solid petroleum jelly for lubrication of the rod.
Although the product worked well in the first days, the result did not last: after a week, the transmission became stiff again.
Upon disassembling the boot and inspecting the system again, the creator noticed that the petroleum jelly had practically disappeared.
He explains that this happens because the product melts when exposed to high temperatures, running off and leaving the parts unprotected.
As the transmission area heats up easily — both from the engine operation and from the sun’s heat —, lubrication ends up being lost quickly.
Silicone Grease Is More Heat Resistant
To correct the problem, the host opted to use silicone grease, highlighting its advantages: the product does not melt, does not damage plastic parts, and withstands high temperatures. He shows the cleaning of the area and the application of the new grease, noting that the transmission immediately became softer and firmer during shifts.
The video also highlights that silicone grease can be used in other parts of the car, such as hinges and door limiters, precisely because it resists heat and remains adherent for longer.
What Not To Use: WD-40 And Common Greases
During the explanation, the creator warns against the improper use of WD-40 or common greases. According to him, WD-40 runs off easily and loses effect in a short time, while traditional greases melt with heat and can accumulate dirt, hindering the performance of the parts.
He always recommends choosing a lubricant that maintains adherence even at high temperatures, ensuring that friction between moving parts is reduced and preventing premature wear of the transmission.
Final Result And Channel Tip
Upon finishing the test, the host demonstrates the result: the transmission is lighter, with smooth and precise engages in all gears. He concludes by stating that silicone grease is the best option for this type of maintenance, as it keeps lubrication for much longer.
In closing, the Mega Dicas Automotivas channel invites the audience to comment on which city they are watching from and to share the video, reinforcing its proposal to provide simple and effective vehicle maintenance tips for drivers and mechanics enthusiasts.
