I have read what seems many posts on other vehicles that towing in OD is bad. I have been towing my trailer that weights approx 4800 with the OD on and have had no adverse a or e ffects, am I on the short road to trans death or not?????

Just to clarify-- you are saying that the torque converter will lock in third gear with the OD off? Do you know what RPM's this will occur at? Does it matter if the ECT switch is turned on or off?cruiser ken said:Always run with o/d off when towing in my 80.
The torque converter remains locked at lower rpm/speed when the OD switch is off which results in cooler tranny temps and therefore better for towing. I've tested this going up hills in 3rd with OD on when pulling about 3200 rpm and turn off the OD the torque converter locks and RPM drops 3-400.
