Have Transmission Questions? Ask a Mechanic for Answers ASAP
My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
From what you have described here this sounds like an electrical sensor or solenoid fault in the transmission itself.This will cause a slow shift if one is acting up and can reset to normal operation for a short period when an electrical fault occurs in the transmission.
What needs to be done from here is to have the fault codes checked with a scan tool to see what codes are set.Then from there the codes diagnosed and repaired to correct this issue.If you can get the fault codes read out from all computers and post the code info here this will help just let me know.
