4L80E lost 2nd gear
#41
Yep, broke/rolled the intermediate sprag and took out the 2nd gear clutches (I think that's what he said).
Decided against going with the super expensive upgrade sprag and just toning down the 1-2 shift. Should be back together and on it's way home by the end of the week.

I don't want to discuss price in the thread since my guy isn't a sponsor.
Jim does all of his trannies with vacuum modulated to remove the opportunity for excessive shift pressures to be set in the PCM, breaking hard parts. Seems ironic now I guess
I understand the principle behind it though. I asked him for EPC and he wouldn't do it.
