3 Questions
1) I believe I read here once that the stock H-Pipe can cause a rattling sound when you rev the exhaust and at various rpms. I had my friend rev my motor a little on the lift the other day and couldn't find any heatshields vibrating or anything - it truely sounded like the noise was coming from inside the exhaust piping in the H- pipe vicinity. Is this possible? .... Gonna have to put an X pipe in aren't I....
2) I tried searching earlier on this to no avail. Forgive me: How high can I expect my stock motor coolant temperature to reach in traffic? I see steady 190 F while driving and today got up to 235 - 240 F in traffic. This really bugs me... Ok or not ok? Owners manual says "....blablabla not in the red you're ok blablabla....."
3) My fuse for the reverse lockout solenoid (M6) is ok (#19 under hood) but still hard to get into reverse. Possible my solenoid is burnt out or is it normal to have to force it a little? When I go to troubleshoot this when should the solenoid be receiving voltage? Baisically should the car be in gear and running?
Thanks guys, Your help is always appreciated!

When I have a hard time shifting into reverse (which seems like every morning), I back out and shift into 4th then 3rd and then reverse.

The sound is from the turbulant air and opening up the hole supposedly eliminates it or atleast enough that it doesn't create the annoying sound.
235 - 240 on a hot day is ok.

Pretty normal. The T56 isn't the smoothest shifting tranny....definitely no Miata. Don't force it. If you have an early C5, you have aluminum shift forks, and you'll bend them, and then you'll mash up the cheap sheetmetal synchro's.

Hello Leaftye,
Do I understand you correctly??? Aluninum shift forks??? sheet metal syncros???
I have a 97 MN6 with problems, (as previosuly posted) going into second, and gear clash going into fourth.
Waiting desperately for your posting of an MN6 rebuild.
Are you near?

Edit: it was really about some crappy aluminum part in the diff...http://forums.corvetteforum.com/show....php?t=1038387
Sure it has rebuild info and info about the shift forks, but while looking at it, I can't see anything that looks like it was made out of sheetmetal, so maybe the part I'm thinking of is really in the diff. As far as my own rebuild, I'm about to get out of the military, so all plans are on hold for a while....unless you can help me pull down a job that pays +$80k for a prior 8 year AF SSgt with programming, networking and ultra high security systems (facility)!

Well thanks guys for your responses! I think I'll still activate the cooling fan with the scan tool at work to verify operation (instead of verifying operation in traffic). My H pipe wouldn't be under the GM warranty still would it? 43k 1999? Lastly, I hope that my shifter forks aren't bent. I just find myself putting it into fifth instead of reverse all the time - and when I take it out of fifth and try for reverse again it feels like I put it right back into fifth, but it'll actually be in reverse.... Gates feel very very close thats all.
