So i bought a 1998 accord lx 4 cylinder and did a transmission flush and treatment. The slips on a cold morning and pop sound when i change from drive to any other gear still happened for a while ( approx. 8 months) And just today ive had high rpms and slow accelerations and now the slips were bad and the check egine light came on had to tow it. I checked to see how the transmission oil is its ok. I need a new transmission but i was just think of doing a conversion to 5 speed since the transmissions are cheaper. Anybody done this before?? how hard is it?? harness issues??
