Ok so I'm swapping my 08 trailblazer transmission and I ordered a remanned unit. The problem I'm having is the torque converters are different. The remanned trannys tc is bigger and sets closer to the edge of the bell housing then the one I pulled. My dad says change the flex plate and it will work. My issue I don't know what to order. I got 2 different Torque converter so I'm unsure if I need oem or something for a totally different vehicle. Thoughts. The guy at O'Reillys looked it up and said the one that came out of my trailblazer is for a 98 blazer/s10. The smaller torque converter.

That sure looks like an S10 convertor to me too.

A lot of times, a custom rebuilder will use a smaller convertor to give the vehicle a lot more acceleration as it is going to be in conversion-mode much easier because the torque of the engine is very powerful on our L6 engines.
That's a way to take advantage of the L6 engine torque by letting the convertor actually do a lot more "conversion" from torque to horsepower.​

Torque turns your wheels from a standstill and horsepower accelerates the vehicle.

But the convertor should have a lockup clutch in it to let you cruise with no slippage.

I'd be VERY VERY suspicious that this original transmission is seriously race-oriented and has been custom built and shift-kitted and PWM-Deleted.

Installing a basically stock transmission is going to be a big disappointment.

I'd get the existing unit re-done if it were mine.
How can you tell its been shift kitted and pwm removed? Sorry if it's a stupid question.

The S10 converter is a big hint, but you'd have to be able to recognize most of a shift kit installation within the valve body. For other hints, you'd have to tear the unit apart.

You'll usually see an enlarged drainback hole in the front seal collection void.

It used to be that real Shift Kits had a small drop-in identification tag that we'd toss in the pan for the next guy to see.

There are "things" that a good bench-guy would recognize quickly:
A 3 inch 2-4 band​
MAYBE a Corvette servo ... some performance builders opt out of this as being too harsh for 2-4 shifts.​
A Z-Pack​
A PWM Delete​
A hardened sun shell​
Maybe a 5 element planetary ... a higher horsepower (read: "torque" here) necessity.​
Replacement of most important thrust washers with radial roller bearings.​
Front seal epoxied-in with a spring type seal retainer.​
A tapered - barrel shaped pump return spring.​
Brass tab-locked bushings replacing babbited, non-tabbed bushings.​
Convertor-depth adjusting washers/spacers.​
Other "Things"​
Thanks for the reply. Most of which I didn't understand lol. But dropped it off at a trusted garage for rebuild. Guy said should run around $600 range.

What's gonna "run around $600.00 range"? A rebuild or put the reman'd unit in?

A $600.00 rebuild is very VERY inexpensive. Are you sure of that metric?
May be a reman unit. Unsure. I dropped Tranny off and guy said be around 600 bucks and around 3 days. It's a guy my dad knows so may be getting a deal as well.
