95 chevy 4L80E torque converter lockup

[6.5coalroller]

My truck is takin forever for the converter to lock up. Prolly taking it a good 7-8 miles jus started the other night. If it sits even for a few hours it takes that long regardless of how hot or cold outside. Used to it would take bout 2 or 3 miles in the morning when it was cold but thats it.

Any other oddities that you have noticed? May want to check your CTS.

uh it actually has seemed lyk it has started a lil harder lately.

Did you change something recently with the wheels?

whats idle like? a little higher than norm. your coolant temp switch maybe going out, as mentioned. I would ohm it when cold and when hot to verify its correct. I have had 2 go out, when it does-no OD, and higher idle.

I agree with the CTS diagnosis. Until it shows your truck as warming up, your lockup just isn't there. You can jump it with a paperclip (temporarily) or a resister when it's cold and try that... if you get easy start and tranny lockup, you found the little carmint.
