I took a newly rebuilt A4L65E out of and a Isuzu Ascender that was working flawlessly, swapped out the tail shaft and put it in my 4th gen. camaro with a brand new 3600 stall. Now the ships are erratic the wand to shift feels like the transmissions binding like the brakes get put on it. All of the sensor seem fine while we're doing tuning the transmission temperature seems fine or getting information back from the speed sensor we know that it's sending out the correct shift points. Does anybody know of anything being incompatible between the 4L60 and 4L65 or maybe the 4L65 out of the. Isuzu Ascender /trailblazer?

 

What year 4l65e?

 

2003 was behind a 5.3

 

2wd ?

 

yes 2wd

 

A friend of mine mentioned the shifter linkage when it was swap could be slightly off, is that even possible?

 

Did you change the manual shaft?
The linkage will be off if you kept the trucks longer manual shaft. You need to change it.
Also with that torque converter it may go into limp mode so you might need to tune the misfire tables.
