S10 Gearbox Slippage

I had a similar issue with my S10. Are you certain about the transfer case oil wear? How did you determine that specifically? In my case, the symptoms were similar – rough shifting, almost like it was struggling to find the right gear. I initially suspected the transmission itself. Did you check the transfer fluid level and condition?

My assessment of transfer case oil wear stems from the fluid's appearance upon recent inspection; it presented with a concerning metallic sheen. As for the fluid level, it appears within acceptable parameters. You mentioned a similar experience with your S10; might you elaborate on the eventual diagnosis and rectification?

Ah, the metallic sheen is never a good sign. My issue turned out to be exactly as I feared; damaged gears in the transfer case that were causing the fluid to break down prematurely. Given your description, it certainly sounds like you're facing something similar. If you're seeing metal particles, I'd advise against driving it more than necessary. You might want to take it to a trusted shop for a proper inspection and potential repair. I ended up paying around 330€ for the repair and replacement. Is it worth keeping going if further wear is happening?

I extend my sincere gratitude for your insights and guidance. Your experience has proven invaluable. Based on your recommendation, I shall endeavor to seek professional assessment and rectification of the transfer case issue without delay. I think a workshop visit is vital for my old friend. The repair cost you mentioned provides a useful benchmark. Thank you once again.
