Surge and engine stall randomly at stoplights

Greetings, I don’t post much here but I do lurk quite a bit. I recently moved my daughter and her 05 CRD to Florida (this liberty previously belonged to ID parts and Frost heaters). It ran well on the 1600 mile trip, but shortly after arriving in Florida it bucked and quit as I came to a stop (just like it would if it were a manual and I stopped without pressing the clutch). In most of my testing it seemed to be happening once the vehicle was warmed and it was parked for an hour. My daughter told me that it did this morning after about a third of a mile (relatively cold) at her first light. It behaved for her all day long other than that. Each time I had this problem it seemed to disappear after a few minutes of driving.

It seems that the problem is related to the TCC engaging and not disengaging when stopping. From my Fiero it feels exactly like when the TCC solenoid failed in that car. I was thinking about replacing just the solenoid pack, but after some searching I found a rebuilt valve body and new solenoid pack from Transmission Parts Now, and I am thinking about shipping that, new fluid, and filters to replace the parts in Florida.

Has anyone experienced a similar problem? Any thoughts on my replacement choices?

It's a torque converter drain back issue iirc. You can prevent the stall by putting the trans in neutral and high idle it for 15-20 seconds.

Fixed completely when I installed a new trans and torque converter.

So you had a similar problem and it was intermittent and somewhat random?

It is a common issue with these transmission with age and miles. The cure is to replace the front pump assembly.
The root cause is described below:

It's been a while, but double check that it's not the fuel filter plugged. If you got a bad batch of diesel, it can cause similar symptoms.

It was a transmission pump problem, the shop that I worked with in Florida (Richmond) reworked my pump and valve bodies with Transgo kits. It works great now and doesn’t have the clunky second shift at lower speeds.
