Is it bad to shift the car manually? Like up or down? Whats the difference between you doing it or the computer doing it? From what I hear going up(like 1st , second, drive) is ok but going down is not.(like from drive to second)
Manually shift the mark?

downshifting "could" damage it, but upshifting is fine.

down shifting with a 98 and newer trans should be ok since you dont have that pos one way clutch. anything older dont shift

After seeing the video with bryan and mark0101 I started doing it sparingly. I don't have a tranny cooler so its not too often, I like how the tires chirp from 1-2. It's something I'll do because I can keep the car in the 2500-3000 range around ricers and the exhaust sounds sweet.

cooler wont matter. the slow shifts make a ton of heat, fast shifts = very little heat build up.
I don't think it matters when you upshift manually. Actually Its better if you up shift when you go WOT becuase it shifts faster. I don't know about downshifting, but I just don't like downshifting since it feels weird. (like about to break the tranny) BTW I have had my 97 Mark VIII when it had 60K and now it has 110K, I drive rough and its still going strong even with me mannually shifting (shifting up...lol)

i always "rev match" when downshifting. Like if i am at 25mph and going into first when i feel it beginning to shift, i give it some gas so it doesnt use engine breaking as much. doesnt hurt it.

Yeah, if I keep it in first running it about 30mph it sounds nice, and then when you nail it she really moves out from a 30 roll in 1st, then I pop it into second around 45, and get a nice chirp. its fun once in a while, but like other posters I dont do it very often for fear of leaving the transmission laying in the road.
Just say NO to manual shifting pre 98 transmissions....
on my 95 mark, I got to 300K and about 5000 dragstrip passes on the stock tranny, but I left the shifting up to the properly calibrated PCM, rather than trying to "stick shift" the Auto.
Jerry said "DONT" and.. I "didn't".

98 being the key difference, the mechanical one way clutch is far superior to the POS they put in the 97 and down cars.
dont want a 93-97 owner to think that because your "upgraded" trans can do it safely that their "non upgraded" trans is safe to do so.

I thought that 7000 rpm was to much for the TC I heard it would start to create a lot of heat and balloon maybe fail

I'm not sure why you would want to manually shift an automatic except to downshift going down a steep grade. Either you're just showing off or you like the ''bang'' - which in a pre-98 stock 4R70W will eventually grenade the one way clutch.
What's that you say? It's faster when you manually shift? Pfffft.
Want performance in your automatic? Do a full J-mod or install a Baumann Re-Calibration kit along with a proper chip. You simply cannot consistently out shift the computer, period.
Want more? Get a high stall converter and practice driving techniques that will lock and unlock the converter on demand. It's like a whole 'nother gear.

like driller said, its NOT going to make the car faster.
the only reason i do it is when roll racing, so you dont have to wait for it to downshift.

Roll Racing, there is a dragstrip here in houston that killed their bracket and index programs {bad mistake) and they started up this "roll on racing".
slow car run from 60mph to 100 mph.. fast cars run from 60-130MPH using a drift box data aquisition system.
it is the GAYEST form of racing I have ever heard of..
we call it the "cinnabon racing series" sponsored by Sure "roll on" deodorant!
These guys build 1000+HP cars that "cant launch" because they will either "blow the tires off" or "break their crappy import drivetrains"..
Roll on racing..tough enough for me, but made for women!
