The springs go in first. That is how my trans came apart and that is how I put it back together. The ATSG manual seems to show it the other way around, but that is not the case.

Check out 4L60-E.com for the aluminum accumulators. Get the pins as well. My pins were worn over 0.003" even with the plastic pistons.

My kit came from Dana at 700R4L60E.com and was put together based on what I wanted and how I use my truck.

 

You have a 50/50 chance then I suppose.
