Al, sorry to hear about your truck. The 22re is one of the best engines around, but it does have several faults. The first is the timing chain. The chain itself is not at fault, but the timing chain guides are. Toyota made them of plastic and they tend to go quite often. The other issue with this engine is valve adjustments. They must be done every so often as the valves have a tendency to stick. You will not hear any noise, but the valves burn out. Ask your mechanic about aftermarket t-chain guides that are made of metal. You may want to replace the following while you are having this work done: timing chain tensioner, water pump, thermostat. Whatever you do, do not anything other than Toyota OEM coolant. It would take too long to explain, but trust me on this one. Also, ask to have the 180 degree thermostat installed. In Japan this is the thermostat that was used. In NA they went to 190 or 195, but this engine has better longevity with the 180 t-stat. I know people that have close to 500K miles on this engine with regular mainetance and using OEM parts (oil filter, PCV valve etc..). The tranny is great other than you may have to replace shift solenoids on the automatic and bushings on the manual. This vehicle and engine have quite a following so don't let this experience change your opinion of toyota as being a reliable (if gutless) vehicle.
