It finally happened..170k modded miles an trans says goodbye
I was hoping to see it hit 200k, but all in all I am impressed with the trannies reliability. The SSEi has been modded since it was brand new and with almost 170k miles the tranny finally said its goodbyes. I haven't driven the car in a while so I'm not sure what it was doing, but my mom said it had been slipping for the last month or so and on Saturday finally just lost all gears. I doubt its any hard parts however and I think just a normal rebuild will do the trick.
FWIW the fluid & filter has only been changed once in this car and that was at 70k miles and it wasn't even a complete flush, all we did was drop the pan. Its had increased line pressure since right around 100k when we put the DHP on which may have helped it actually.
But can't complain about 6 years and 170,000 miles of service with mods in a car that heavy, especially since basically no maintenance had ever been done to the tranny. I'll let you know how the new trans works out. Its just going in to a local trans shop for a normal rebuild.
