1982 Celica 242000 miles. Colorado. I have weak power and some transmission jumping back and forth when going up hills. Other problems include vapor lock. Fuel filter is clean. Trans fluid is not low. It might be a little high. Is this my transmission giving out or is it more likely to be a gas problem? Thank you!! Mark

transmission getting weak.

325,000 miles,, jeez,,,, need a rebuild on that engine. You walk that far and tell me how you feel, worn out im guessing. new set of rings and bearings and give the poor thing its bang back. give it a compression test to confirm but my moneys on low compression ie old engine

May have to look for these journals at shops that handle high performance parts or find a machinists that does this kind of work to mill you some.

sounds like it is out of time for the running part and it could also make it run a little on the warm side

Not starting is not a clutch problem. Could be the battery, or the starter. You need to see a mechanic.

take it back to where you have it rebuilt soumd some thing was not fix properly

thermostat faulty, leads to motor overheating result blown head gasket.Is there water comn out of exhaust, Is oil discoloured on dipstik?

There is a recall for valve problems. The warranty for this problem has been extended to 100,000 miles for that. Check with your dealer to see if that is the problem. If no help contact GM.

Try the vaccume control module on the transmission. That is the likely culprit.

They are not taking him for a ride. 2000 model year and back timing belt replacement intervals are recommended every 60,000 miles. 2001 & up is reocmmended every 90,000 miles.
Yes, the car will be running good, but, the timing belt does get weak over time, and can break or "jump time" (jump a tooth or 2), at any given moment, with NO warning.
Yes, do get the belt changed.
BUT: 800.00 is a lot of money. TOO much money, IMHO.
The flat rate on that engine is 4.0 hrs. At my labour rate here, That equates to $280.00 plus a $50.00 belt. I get roughly $350/Celica belt replaced total; w/o a water pump upsell.
$800.00? Exhorbitant. Looks like the shop is charging you $185.00/hr. Find another shop.
That price is not robbery, it is rape.
