5R110W Delayed R/D - New Torque Converter
Hi, I'm looking for thoughts/advice. A few weeks ago, my transmission started acting funny after pulling a trailer, there was a delay shifting into forward or reverse, a small delay in the 3-5 shift, and while it still shifted from gear to gear, it didn't seam "normal". At any rate, I didn't have time to get it checked out and while pulling a trailer a few days later, it started making a noise like I was leaking boost, it started getting hot (~180F), and then the TOW/HAUL started flashing and I got a P1744 code. I had it towed to a local trans. shop and he replaced the torque converter.
Driving 3 hrs. home from the trans shop and the following week, it's been shifting fine and seems more "normal" but I still have the delay in shifting into forward or reverse. I initially thought it just needed a relearn and I disconnected the batteries to initiate the relearn. However, I still have the delay. This delay happens EVERY time the truck is started, irregardless of whether the transmission is cold or warm. And it only has the 1 delay when initially shifting into R or D, but any subsequent shifts into R or D are immediate without delay. For example, I shift into reverse to back out of my driveway, which takes a few seconds, but the shift into drive is immediate. But if the engine stays running, there is no delay from P to R/F.
I'm at a loss for what I should do next. After the initial delay, transmission seems to shift fine. But I'm worried that continuing to drive it this way will cause damage. Is the shift delay at all related to the failed torque converter? Should I be looking at replacing solenoid(s)? Truck has about ~200k miles. And while I don't tow a lot, I do from time to time and I don't want to be stranded again.
Thanks in advance for any help/insight.
