4L-30e or a340?
I have a 93 Bighorn 3.1 auto originally from Japan. Suupercheap auto have 2 transmission filters listed for the Bighorn, 1 for the 4L-30e and another for the a340.
The parts guy said I had the 4L-30e as the other was a 5-speed auto.
Part numbers are:
4L-30e = RTK25, a340 = RTK41. The RTK25 is only $50 too
