Exclamation Tranny knowledge wanted!

Is there a certain reason why my 1st-2nd shift is very hard and jerky? Every other shift is smooth as butter. Would a VB help? Tranny was just rebuilt less than 10k ago. Mechanic said it was a HD version, it does hold power decent ( just a 2.2k and banks chip, we'll see with custom tunes when I get them) but that first shift is rough, is this normal for beefed up trannys?

Also, how do I know when my TC is locked? Is it looked up to OD or only in OD? Around 55mph if I hit the pedal truck seems to stall then RPMS jump up and I'm gone, is this the TC locking?

I can't afford a BTS but I would like to have a trustworthy transmission, what's a good way to beef up a stock rebuild?
TC,VB,6.0 cooler? What brands?
Thanks for any help guys just tryin to gain more knowledge!

6.0 coolers are i believe almost 3 times bigger then the stock 7.3 cooler. that will be a good start.

as for the problem. what to you mean jerky? like just slams into gear. or actually jerky as in grabs and releases several times? if that makes sense

Yes sir, slams into gear. Kinda like a slight stall then it grabs and jumps forward. All other gears shift flawlessly

Has alot to do with the tuner imo, once I had my tw reburned the 2nd time then everything was all good.

I'm quite sure it is. I'd have custom tunes by now if I didn't just have to redo my whole front end.

Mine does the same thing.I have my line pressure jacked up also.Without the tuner,it has a very firm snap too.We also drilled a few passages for better distribution.BTW..I have stock VB(drilled of course) and transgo tugger shift kit..Billet Triple Disk converter.
