A904 Transmisson deeper oil pan questions

One of the benefits of the deep pan is keeping the trans fluid cooler because there is more fluid to absorb heat.
Downside is that a deep pan is the best speed bump killer you can get....
If this was my car:
- use the stock pan & next time you remove it, fit a drain plug.
- in the meantime, up grade the trans cooler capacity to keep the fluid cooler. I had two coolers on my car at one time. If you use two, connect them in parallel, not series.
