I saw this posted in the 1545 failure poll and was surprised to see it wasn't repeated here:
Not exactly the thread for this, but I'm trying to (discretely) spam this info I just found about AT 1545s:
For those 1545s with serial #s GREATER than 321-101-6535 (or retrans GREATER than 9108-0912-20), there is a newer option for the front pump. This newer option involves replacing the front pump and stator. It retains the lockup. Darpco in Dallas (likely among others) can assist with this.
