I have a 1994 astro that I swapped the trans a few years back and did not reinstall the flywheel cover/shroud, now I just failed inspection and need to find a replacement. does anyone know what model the auto trans w/ overdrive is? I dont remember. also anyone know if a cover from any other model trans should fit?

700-r4. Check Ebay. I actually did a swap in my van too. Luckily, they don't do inspections around here, so I left the cover off as well. That thing is hard as hell to get back on!

Here, I did the searching for you. It's the only one I could find on eBay.

Your tranny is a 4L60E which is the electronic version of the 700r4/4L60. 1993 GM switched all rwd passenger vehicals, 4,6 and 8 cyl to the 4L60E. The inspection covers should be the same though. Good luck!.

if its a tin one anyone will fit if its aluminum only 4.3/5.7 will fit, go to the local junkyard not ebay.
