Put in new flywheel on a 98 chevy k1500 5.7 L and now it doesnt shift. i thought i had the torque converter seated right but now ive heard it icould be the cyliniod or shift componits on the transmission. any help would be great.

never knew that a torque bolted to a flywheel, it is always bolted to a flex plate that drives the torque converter and carries the ring gear for the starter
there are washers that fit either of that flex plate or on some engines only on the converter side with the bevelled edge facing away from the plate
the torque converter is bolted to the flex plate by 3 or 4 bolts facing back to the converter from the block end
why are flywheels not used with torque converters
the mass of the flywheel affects the engine acceleration and the torque converter full of oil takes over that job so the engine acceleration would be considerable slower if both were used

typically when a torque converter "GO's" it disintegrates and sends little bits all thru your trans and stops up the works , you could clean itna still have to disassemble the entire thing , and ive heard of folks cleaning the solenoids (gear selection) blocks before , but I sure don't recommend it , just replace em

On a newer car this is a mode the transmission goes into when there is a bad problem with the transmission. It will usually go into 2nd gear where you can drive it safely to get it checked out but will not shift into any other forward gears.

You need help. Someone with experience needs to check that the torque converter is fully seated in the transmission.
This is an automatic, isn't it?
If it is a manual transmission, the clutch disc has to be centered with a plastic alignment tool, so it all fits back together.

most starters are the same on chevy 350s should bolt right up, if you have to change torque converter, but most chevy 350 flywheels are universal. that's the good thing about a chevy most everything 350 smallblock bolts right up. hope this helps

The books say no. If all the electrical connections are the same, go for it but look at them closely. Also you will want to use the flexplate (flywheel) from the donor vehicle. It was right around 98 or 99 that Chrysler changed the bolt pattern on the torque converter. Chrysler motors are balanced by the torque converter, and this means the four converter bolt holes are not evenly spaced, and must be in the correct alignment to get all four bolts installed. one of the holes in the flywheel has flat sides. If you get that bolt in, and any other bolt in, the other two will go in. if you put that one in and the next one won't go, you need to remove that bolt and rotate the converter to the next hole. do yourself a favor and turn the converter the same way each time to avoid trying positions already tried.

sounds like the torque converter or the flywheel bolts have backed out or the dust cover has got bent and the flywheel bolts are hitting the dust cover

will the enging start? Check the flywheel to be sure it isnt broken. Pull the inspection cover under the truck and see if the torque converter is still bolted to the flywheel, there are only three bolts and they will break if they get loose. If both of these check out ok then the trouble is probably internal, and will require removal of the transmission to repair.

theres a good chance that it broke the main shaft in the tranny from to much pressure forcing it back, be honest i would look for a good reman tranny and if your having problems with the starter to close to the torque converter they make shims for the starter to avoid that problem.

I would say about $200-400. It involves disconnecting the transmission and torque converter bolts to the flywheel (3 bolts) and moving the transmission back far enough to remove the flywheel.
