trans swap on a 2.2L base model

[JLbeast]

Right on. K now something almost the same, can I swap for a better auto trans? I have the base of base models, if my info is correct, it's
A 3 speed with electronic overdive.

And I know they have a 4 speed. Is this again a rediculous thought?

What about a ecu and harness from an lt xfe?

Keep your harness and ECu and you can swap in the 4t65e.your trans 4t45e.there both 4 speeds but for the price,you can have your 4t45e built with stronger clutches and bands and top it off with a HPtune(2007 and up only) or trifecta tune to raise line pressure for nice firm shifts.remember your stock 4t45e can handle up to 350WTQ.My buddys turbo auto was right around 300 wtq and his trans ended up going out.The extra stress fused some clutch plates together and cracked the clutch basket and the 2-3 shift solenoid got stuck so he only had 3rd and 4th if it wasnt slipping.
