Have a 97 Suburban k1500 will not down shift engine does not rev up like transmission is slipping. Seems to get worse after driving for a little while. Wont even go up the smallest hill. Ive had it at the mechanics twice, they thought it was timing, replaced the cat converter, exhaust manifold, serviced trany, throttle position sensor, fuel filter/ pump etc, still problem exists.
have the same problem?
