I am a newbie so I hope I am not repeating a previous post. I have done much reading but am still unsure how to proceed so please bear with me.
I own a VW Golf MK4 1.8-20V 1999.5 which I bought about a year ago so I do not have the car's history.
There is a delay when changing from gear 2 to 3, the revs flare and then gear 3 engages with a not so slight thunk. Sometimes (usually when cold) it sounds like it does not want to engage 3rd and I have to either ease up on the gas or give it more gas to get gear 3 in. At higher acceleration, gear 3 engages with a noticeable delay but without the thunk (makes me want to race all the time).
I have had it scanned for codes and got a few unrelated codes such as airbag, air-mixture ratio and abs which I have since cleared. I have also had a damaged transmission wiring harness which put me in limp-mode but I have since repaired that. Scans now come up clean
I have had the ATF fluid changed and the pan dropped and there was not much residue. However, I cannot tell if the previous owner had already done the same.
Has anyone resolved this (especially the thunking) with either a solenoid change or valve body rebuild? Or am I looking at a new trans?
