Today I took out my Stang for the first time this year and I had two problems.
1.I just had the tracloc rebuilt last year with extra clutches and 3.89 gears and when I put down some rubber for the first time today it left one strip on the right side.it worked perfectly last year.Then before I went home I stopped in a secluded area and did a nasty burnout and it left TWO nice black strips.So what I wanna know is why did it do this.I used non-synthetic fluid and Ford friction modifier.
Problem 2 is with my C-6 tranny;
I have a TCI c-6 with a reverse manual valve body.Cant remember the stall on the converter.I use type F fluid.The problem is when I shift to 2nd gear it doesnt feel like it shifts into 2nd gear unless you really have the engine revved up.And even then it doesnt always do it. Just cruising around you cant feel it at all,no drop in rpm either.But when I downshift from third it really feels like it downshifts.It started doing this towards the end of last year.Is there any adjustments I can make? The tranny has less than 1000 mi.and no dragstrip passes.Although I do romp on it a bit.
Any help would be appreciated.
Thanks in advance.
Bob

Bob I think the vacuum mode controls the upshifts.You can adjust it to shift at different RPMs.Thats just my guess?

Scoop I appreciate the help but there is no vacuum used on a manual valve body.I was thinking of trying to adjust the intermediate band that controls 2nd.what do you guys think?

I hope some one smart comes along soon.

The tranny thing i have no idea...it's one of them slushbox types.

If you hadn't driven it far or around many corners since being apart the rear end slippage could be from having fresh oil between the clutch plates which slip the first time till the thick film of oil shears off.

That sounds like a good explanation Tom for the rear.I'm not too worried about the rear I'm saving up for a new rear with some good axles and a locker.
As far as the trans goes I emailed TCI and Will said to check the band adjustment and make sure the servo was modified correctly.If I can find some spare time soon.LOL.
I really want to convert to a JW Aluminum bell and a PA super comp C-4 but thats gonna have to wait for a while.I'll keep you guys posted and thanks for the help.I learn something new everyday on here!

Well I figured out what the problem was with the 2nd gear in my C-6.
When I changed the fluid and gasket because it was leaking last year I didnt reinstall the linkage the right way.I crawled under and readjusted it and second gear hits as hard as ever.I love it.One problem down one to go. I'm glad I didnt screw anything up.

Get rid of the friction modifier. It's only for going around corners. (seriously)

Ok Alex I'll get rid of it. If I drain the fluid out what do you recommend to put back in? Remember I do drive the car on the street.Also I dont want to spend the money on synthetic now because I plan on redoing the rear with a locker of some type. this is only a temporary rearend until I get some more funds together.But It would be nice to have a posi.The trac-loc was built by a trusted buddy of mine with additional clutches installed. It was working fine last year but I cant remember if that was before or after I put in the friction modifier.

Any "name brand" 85w-140 will do.
Most are about $3-4 a quart.

No kidding??? Mine light 'em both up
Will running without friction modifier increase or decrease clutch life? Oh man, I've got $50 worth of synthetic gear oil in that thing

Friction modifier makes the clutches slip when they feel any resistance like when cornering.

So, Alex, basically you are saying that for performance use one should not use friction modifier, right?
