This makes no sense to me? Why would the TQ lock up in 5th and not forth gear? I would think it would be less stress on the trans to drive in 4th gear instead of 5th where it would be hunting for a lower gear often and it would generate more heat shifting often?CPLTECH wrote:According to the service manual, the torque converter only goes into lock-up in gears 3 and 5, never in gear 4. So extra heat is generated while in gear 4.
