1994 Toyota Corolla 1.6 lt.3 spd.auto trans.The manual says that I must match mark the torque converter and drive plate before I seperate the trans from the engine so that when it goes back together the dynamic balance will be maintained.Problem is,I am putting in a different trans that has not been match marked.How do I determine the proper line up to insure balance?Thanks!

You don't but I can offer a small suggestion. The square metal pieces on the converter are the balance weights. See if they have left a print on the flexplate.

If so line them up so the match the converter. If not "wing it" it isn't going to make that much difference as you don't have a 10,000 RPM engine! Good Luck

Suggested Repair

Look for impressions left on the flexplate by the square balance weights on the torque converter and align the weights with those marks if present. If no marks remain, approximate alignment is acceptable on this low-RPM engine.

Conversation Summary

The owner of a 1994 Toyota Corolla is installing a different automatic transmission and cannot match-mark the torque converter to the drive plate as the manual requires. The expert advises checking the flexplate for prints left by the converter's square balance weights and lining them up if present; otherwise, exact alignment is not critical because the engine does not run at very high RPM.
