It's B2 time!

[Strand]

As some of you may know, I've been dealing with a somewhat buggy transmission on my 84 300D for over a year now.

At first, it wasn't too bad. The initial post-purchase hesitation and erratic shifting patterns (as well as most of the flaring) were massaged out thanks to a thorough overhaul and adjustment of the vacuum system, and for a hot second it looked like the transmission was actually alright.

But the flaring wasn't fixed. Essentially, these were the symptoms:

• Car shifts into drive fairly quickly. The engagement isn't as firm as it is when shifted into reverse, but it's definitely noticeable and the car will creep.
• If light throttle is applied, the car behaves and shifts normally through the gears
• Under heavier acceleration, or when starting on an upward incline, the car would lose forward gear, leaving the engine to rev freely before eventually (sometimes) catching back into gear.
• Once the car gets into 3rd and moving faster than 25MPH, it's all smooth sailing.
• Reverse works perfectly.

Recently, things have gotten progressively worse to the point where the car is barely drivable: the transmission slips out of first with the slightest application of the throttle, and the drivetrain shudders a bit as it slowly catches 1st gear and builds up speed. If I lived in a flat, rural area with empty roads, I could potentially live with it, but it's just not an option in Brooklyn.

I've spent a LOT of time reading through all of the B2 related literature I could find in the past couple of days, and I'm 99% certain that my earlier assumption of a B2-piston failure is the cause of my problems. I'm assuming that it's the piston and not the band, as the car still engages forward drive, creeps, and reverses perfectly. And like before, once I'm in 3rd/going 25+, things are fine. All off this also seems to indicate that the transmission is not completely toast (fingers crossed!)

Everything I've read suggests that a failed band would result in no forward motion whatsoever--no engagement, no forward creep. For everyone who's more familiar with B2 issues than I am, is this correct? A snapped band would unfortunately put me in the market for a replacement transmission.

I've ordered the parts required for the piston job, and I'll keep everyone updated with further progress as we go along.
