Know Your Patient
One would think the easiest part about working on transmissions would be identifying the model you are working on. Nowadays, unfortunately, it’s not always that easy. I was helping via e-mail a technician on a transmission forum who reported having issues reaming a late-model Chrysler FWD valve body. Both he and I were thinking 41TE (A604), but that turned out to be incorrect. What he was working on was actually a 41TES, also known as 41TE VLP.
