Question

Answer 1

P0738 3-4 shift malfunction

If the transmission valve block has been replaced this leaves you with the TCM or the transmission itself where the problem resides,If the transmission voltage for 3-4 is low this will leave you with 3-4 shift malfunction and will be the TCM , if the voltage is correct the transaxle will need to be replaced.
