Re: Transmission Over Temp Message 4.7 WK
A very attentive person can count the shifts by watching the rpm drops. When the torque converter locks, it may feel like an extra gear depending in when it occurs. If you know this behavior and test drive it, you can tell if the TC is locking. Another symptom is rpm rising out of proportion to speed when accelerating lightly at speeds above 50mph or whatever the lockup speed is. These are general rules not specific to a certain transmission.

His family has started a fund on giveforward.com. If you have ever been helped by someone else, now is a good time to pay it forward. Here is a link to that page. God bless you! http://gfwd.at/1rz33PW
