After reading through
@L8T BURB thread, I decided to swap out the broken L86 (Thank you GM DoD) out for the L8T. So far smooth sailing, separating the l86 from the 10l80 required a wood chisel to wedge in and work around the block until they separated. Now that the new L8T is set in place there is about 1/4" gap between it and the trans and I'm wondering if I'm going to have to use bolts to pull them together. The torque converter spins freely and I don't see anything that may have been caught between the two. If I use a pry bar to rock the motor up and down, they pivot on the dowels but won't seat all the way. Thought?
Whoa up! I broke a transmission pump on my Chevy forcing the engine and trans back together.
There are 3 spline sets that have to line up with the deepest being the trans fluid pump. If you are successful pulling the two halves back together without breaking the mounting flanges on the transmission, the loud pop you hear will be your transmission pump breaking.
On the SECOND installation, I had a friend rotate the engine slowly with a breaker bar as the transmission was close, like yours, until the crank splines lined up and then it seated easily.
It's been some years since this project and maybe others here have more recent experience. There may even be some YTvids to show the best process.
You don't want to have to do this again.
