SUBURBAN SEEMS TO BE OUT OF TIME AFTER I CHANGED THE TRANSMISSION
I HAVE A 1999 SUBURBAN WHICH I JUST REPLACED THE TRANSMISSION IN. I WENT TO START IT AND IT WOULD NOT START BUT SEEMS TO LIGHTLY BACKFIRE THROUGH THE INTAKE. IT SEEMS LIKE IT IS OUT OF TIME. I HAD LOOSENED THE DIST CAP AND COCKED IT TOWARDS THE FRONT OF THE ENGINE TO PREVENT DAMAGE BEFORE I SET EVERYTHING LOOSE BUT ENDED UP DAMAGING THE CAP ANYWAYS. I REPLACED THE DIST CAP AND BUG CHANGING ONE WIRE AT A TIME. SOME MECHANIC FRIENDS OF MINE THOUGHT THAT I MIGHT HAVE PINCHED A WIRE BETWEEN THE BELL HOUSING AND MOTOR. COULD THIS BE MY PROBLEM OR DO YOU HAVE ANY OTHER SUGGESTIONS WHICH ARE HOPEFULLY EASIER TO SOLVE THAN THIS ONE.

If there is a pinched wire you will be able to feel/see it. If the dist cap got damaged, then it is possible the distributor got bumped or bent during the changeover. The first thing to do, is check, and recheck that you have all the plugwires at the right places. (18436572) Make sure that your wires are set in this order on the distributor cap. If they arent, then there is your problem. If they are set right, then check your timing. Or have one of your friends come redo the plug wires, and timing from scratch.

check transmission fluid level,could be very low transmission slipping not going into over drive.if been long time change transmission fluid and filter.if transmission fluid filter already been changed other problems cause transmission not to shift could have worn broken need adjusting.governor valve sticking, governor drive gear worn, governor weights or springs missing or damaged. you could have sticking first and second shift valves.your first and second servos pistons seals stuck or damaged. do fluid change and add some high mileage transmission treatment go to any auto parts stores find transmission additive that will loosen up transmission sticking shift valves in the valve body. if your check engine light is on have vechicle code scan for faulty tps in which will cause transmission not to shift over drive.
unfortunately what it sounds like is the transfer case like you suspect. inside are bearings and gears and a chain what happens is the chain will stretch and cause this problem it will actually jump the teeth on the gears, you will need to have the chain replaced in the transfer case. sorry to have to tell you this but i hope it helps.
I have a 99 GmC Suburban, an it had the same problem, I replaced the fuel filter, still had same problem, then I replaced the fuel pump, that fixed the problem for one year, I had to replace it again, this makes my third replacement, the first two pumps mad a whistling sound all the time, the last pump did not sound at all it seems the pump was improved, also came with a new and better connector.hope this helps...
Check the tranny filter and make sure it is clean. If not clean it out and put it back in. Sounds like it is just not shifting right. this could be the problem. Also try first just checking fluid level with the car running.. If it is low it could cause this too..
this sounds like you have a problem with the electric fuel pump sticking, that would be where i would look, when u turn the key on with the windows up do u hear a humming noise for about 3 seconds? if not the fuel pump is the problem.
I HAD THE SAME PROBLEM WITH MY 1999 GMC YUKON WITH THE 5.7 ENGINE HAVING TO JUMP START ALL THE TIME TO GET IT RUNNING, THE PROBLEM WITH MINE WAS THE FUEL PUMP HAD TO BE REPLACED, EVEN WHEN I REMOVED THE PUMP AND TURNED THE KEY FUEL PUMPED OUT BUT WAS NOT ENOUGH PRESSURE TO GET AND KEEP THE ENGINE RUNNING.I ALSO TRIED STARTER FLUID, THE ENGINE WOULD RUN UNTIL THE FLUID BURNED OFF.SO THE SOLUTION FOR MY TRUCK WAS THE FUEL PUMP AND NOW ITS STARTING LIKE A CHAMP
