Maybe I missed it, but I have still not seen an answer as to whether the converter will lock up in "3" , or only in "D" I see where it won't in T/H mode, but what about in regular "3"? Also, I could swear I have seen my 2008 converter lockup in T/H. After the 3/4 shift, I would then see the RPM drop again...... C

My question never got an answer....

Ok, one more question. In reference to the "Tow in 3 or D" question, you stated to run up speed enough for converter lockup. That I understand, but will the coverter lock up in 3 also, or only in D. C

------------------- "One of the other problems that I found on the 4L60E transmission was overheating from towing. If you tow, you should definitely consider getting a Hayden(or comparable) transmission cooler. Your torque converter takes a huge amount of abuse when you're towing and also put out a large amount of heat. If you drive hard, this should be one of your first modifications to the truck. If you overheat a transmission bad enough, you most definitely will be rebuilding that transmission and torque converter. Expect a $1500 to 2000 bill. Possibly more if you drive it until it stops" -------------------- Does this mean the factory installed coolers with the trailer package (Z82) are not good enough, or are you talking about trucks with no cooler at all.
