It has been hot (90+) here the past few days. When the transmission gets up to around 160 degrees fourth gear either kicks in late or I have to back way off the gas for it to engage and at times I am just barely on the gas. All other gears engage with no problems. It's not slipping from what I can tell in fourth gear and the torque converte locks as it should. If I tap the brakes to unlock the converter I have to back off the gas a little to get it lock back. At anything below around 155-160 degrees the transmission works just fine. When its not hot it kicks into 4th just fine and the torque converter reengages without me having to back off the gas. Any ideas or suggestions? Thanks!

Codes?

Mileage?

Last trans service?

No codes have popped up and Autozone didn't see any pending codes. It has 100,6xx on it and the transmission was last serviced (fluid and filter) about 2 months ago. It has been fine since I did the service until the last week or so when it's been hot out.

Lets think about what has changed.

Had it been as hot as it is now before you serviced the tranny? If so, did it act funny then as well?

Do you think when servicing you could have installed the filter wrong, stirred up shit from the pan, or damaged the valve body somehow?

It hasn't been this hot since last year and it was fine then. I'm pretty sure I got the filter in correct. I heard and felt it click into place inside the valve body just like the last time when I did it. I doubt I've messed up the valve body but it is possible. I didn't mess with anything on the valve body itself. I just did a simple fluid/filter swap.

I ran across this article today when doing some google searches: http://pages.prodigy.net/transman/_import/pages.prodigy.net/transman/index7.html

He talks about the torque converter not locking up after the trans fluid reaches 140. He mentions the valve body in his article. I saw this on eBay and thought maybe it could fix the issue but don't want to drop the cash on something that MIGHT fix it. I know the trans-go shift kit mentions about fixing a no lockup or 4th condition. I also wonder if that could fix this.

More than likely I will end up taking it to one of the trans shops here in town that does free diagnostic and has a good reputation with those I have talked to.
