M20, Auto box with no electronic switch, mechanic has diagnosed over phone that the torque converter is u/s, and will be inbetween $1000 - 1800 AUD to repair/replace. Haven't had time to get in to see him.
Symptoms that i have is when i reach 80-90kph, the gear box changes into 'lock out' like a fifth gear. When it does this i get an initial noticable vibration that continues slightly, and the car feels like it is surging slightly. It started doing this gradually, and I have noticed a little tranny fluid on the front outer gearbox casing. No other problems with the gear box, still feels as strong as ever and shifts well. Only other recent problem that may be associated is my rear muffler has developed a large hole at the inlet pipes. Is it possibly just a seal that has failed on the torque converter, and also does that seem an excessive price on repairs.
Thanks
