CAPSAT

sirs am located in city of Karachi in Pakistan. the local scrapyards are ready to supply me a K50, with a 2 weeks warranty for any humming or grinding noise, if there is any noise of humming at any speed they will take back the transmission. am skeptical when i made a condition to drain the fluid and refresh new at my cost before i pay 75% and take delivery, every scrapyard with K50 declined that. we have smart scammers into automotive parts business specially at scrapyards. I was wondering what if they poured in a thick viscosity tranny fluid to hid whining / grinding noise and later when i flush the fluid i end-up at 100% loss. is that condition of mine to refresh new transmission fluid unreasonable.? our market (Pakistan) is almost non-existent with vehicle Transmission rebuild shops., so opening up a transmission to rebuild as DIY i will end up stuck with new parts not available. please guide me how can i test for noisy transmission out of vehicle., please Oct 19 2022
