I have a 1994 camaro with only about 10,000 miles on the rebuilt engine and GM remanu 4L60E. Also has a 2200 stall.

The past few days I have noticed mainly if I get on the gas at all then the transmission from that point has issues shifting into 1st and 4th. I get on the highway to come to work at about 65mph and the tranny wont shift so the motor is running at 3k RPM. Then once I slow down it shifts down but then it will stop at 2nd so when I go to take off it takes more gas since it isn't in 1st.

The part I have not figured out is that if I pull over, put the car into park, turn off the car then restart it then it will shift just fine again.

Thanks in advance for any help

 

Got home and looked for codes and it has a code 75 - Transmission system voltage low

The fuse is good, the pink wire that the manual says to check is good so not sure of the issue at this point.

Any ideas?

Thanks

 

I had the same problem and it was the ignition switch.

 

Really? I guess thats good and bad. Its an easy fix but I just replaced mine about a year ago.

 

I just wanted to update that so far after 2-3 days of driving after I replaced the ignition switch the problem has not returned.

Thanks

 

Glad to hear that!!
My transmission had the same symptoms as yours except that mine also wouldn't shut off with the key.
