Question about Chevrolet Cars & Trucks
I am going to change the tcc pwm and cs hopefully that works
This should help you,P0894 https://www.youtube.com/watch?v=R5Sy5YMlFrw
P0741 Torque Converter Clutch Circuit Performance or Stuck Off
this also refers to P0894
all vehicles codes from 1998 have the same coding bar for japan and other countries that use different coding, its best to have the codes rest and go for a drive just to see if it is just a glitch.
The list of what could be wrong.

On many engines with distributor less ignition systems and sequential fuel injection, a camshaft position sensor is used to keep the engine's control module informed about the relative position of the crankshaft. By monitoring cam position (which allows the control module to determine when the intake and exhaust valves are opening and closing), the control module can use the cam position sensor's input along with that from the crankshaft position sensor to determine which cylinder in the engine's firing sequence is approaching top dead center. This information is then used by the engine control module to synchronize the pulsing of sequential fuel injectors so they match the firing order of the engine. On some applications, input from the camshaft position sensor is also required for ignition timing.
The camshaft position sensor may be magnetic or Hall effect, and mounted on the timing cover over the camshaft gear, on the end of the cylinder head in an overhead cam application, or in a special housing that replaces the distributor (in the case of some of the GM applications). Operation and diagnosis is essentially the same as that for a crankshaft position sensor.
Re check the wire harness and the sensor installation to the camshaft sensor in Bank #1 which is where the #1 cylinder is. Good luck and hope this adds some light to you question, keep me posted and be glad to help.

SOURCE: replacing pcv valve
driver side valve cover in the back of the cover. if it even has one, sometimes the cover has been replaced with a later style that uses a baffle instead of a pcv

The MAF is almost certainly not the issue, as it would tend to generate other codes and more severe drivability problems. If the rebuild did not include replacement of the TCC solenoid, then it may need to be replaced. It can be tested by applying battery voltage to one lead momentarily, while the other side is grounded. If the connector is a single lead, clip a ground to any metal part of the body of the solenoid, or leave it installed when testing, if possible. If it is a double lead, reverse polarity once when testing. If the solenoid does not click or move, regardless of polarity, it is bad. You can also test the resistance across the solenoid. Use a known-good unit to determine appropriate resistance. Your dealer may be willing/able to tell you the appropriate value. If the unit being tested is very low or much higher resistance compared to the reference unit, or if the meter shows no connection, it is a bad solenoid. The test unit resistance should be within about 10% of the value of the reference unit.

there is a petcock at the bottom of the rad drain ti from there and use a antifreeze tester to check protection temp
