Default 4l80e w/ 5.3 Help!

Also posted this in the trans section. Figure I'd put it here too.

I'm using a 95 4l80e in my mustang project w/ a 5.3. I have a protorque stall converter. I bought the tci 4l80e flexplate thinking it would work for me. I have a gap in between the flexplate and the converter when I install the trans.

Do I need the gm spacer? My concern w/ this is that the starter won't reach far enough? Am I right in that assumption?

I have the pilot spacer installed that came with the flexplate. I could remove it, but I don't think the converter would be fully seated when it slides forward.

Any help would be appreciated.

You'll prolly need the GM spacer, sounds like you have the 5.3 engine from a car with the short crank (flush with rear seal). Is your gap around 0.41" - 0.43"? The spacer is 0.400" and you'll need about 1/8" to 3/16" add'l clearance. If so, replace the pilot spacer with the full GM spacer.

The 5.3 I have is from a 2004 silverado 1500. I'll do some measuring tom.

The thing is I'm just worried my starter won't reach if I put that spacer behind the flexplate. Am I wrong?

You also have to have the flat flex plate, then the starter will work.

I'm pretty sure the flexplate I'm using is about as flat as one can be haha.

Thanks for the input guys. I will order the spacer (and longer bolts) and go from there!
