I pulled out my 1.6L engine (without the transmission) from my 1994 Corolla and then went to install a 1.8L engine and it did not mate up (as far as I could tell) to the transmission. Is there a different transmission for the 1.6L than for the 1.8L engines? I spent all day Saturday trying to make it mate up and it seemed like there was too much space between engine and transmission. The bolts would not reach thru. Is there a different tranny? It almost seemed like the torque converter was too thick, otherwise it would have been fine. I was hoping for a simple engine swap, and it turned out not to be simple at all. Should I pull out the 1.8L and put in another 1.6L or change the transmission (if it is a different one for the 1.8L)? Someone suggested I pull both engine and transmission out and then mate them up prior to re-installing them - will that work?? Anyone have any experience here??
