I took my wife’s car into the dealership for a warranty a few weeks ago and while they were checking stuff, they said the car needed 1300 dollars of work (piston soak and replace some transmission parts). I ended up doing the soak with my grandpa and took it to a shop for the transmission (wasnt even an issue, just a rivot replacement on a wheel well cover) and ended up saving 700 dollars after accounting for tools, jacks, jack stands, etc.
I want to start working on my own cars for things that can be done easily without expensive specialized tools, and I might be buying a house in the next year. I just want to start getting a decent collection of tools to hopefully save money in the long run.
I currently have a huge range of screwdrivers, soldering equipment, plyer set, socket set, file set, wire cutters and a small tool kit with some misc stuff.
I am mainly looking towards a torque wrench and a good spanner/wrench set, but looking for suggestions on what to get. Holding off on power tools until I wrap my head around brands and batteries.
For working on cars on stuff as complicated as transmission swaps, you have to know what you are doing, but look into a QuickJack.
In other regards just start with a few basic tools and get more as you need them. You can justify buying a $100 tool if it saves you from e.g. a $200 replacement item or shop repair.
