lsvtec

has only done it twice....

checked all grounds, they are proper.

checked vtec solenoid it is proper

some reason the car powered down during power shift, then came right back on.....

new coil , new cap n rotor in distributor...

everything is new, spark plugs, wires...

any inputs apreciated.

 

What do you mean by power down?

 

If by power shifting you mean shifting without closing the throttle (which by the way is murder on drivetrain components), you probably just experienced the transmission having to yank the engine RPM down way lower than it was in the previous gear (and from the engine RPM having shot up as you released the clutch to shift but kept the throttle open).

I have broken transmissions trying to power shift. I don't recommend anyone do this.

 

man I've done this sometimes. guess wont no more. btw how much faster can you get by powershifting at the 1/4 track?

 

Clutch wont like that much either. It would make it a bit faster till the time the clucht goes or an axle snaps.

 

Extremely dumb idea OP.

 

Double clutch son didn't u listen to vin diesel?

 

In most cases it makes you SLOWER because your synchros end up not being able to keep up with the engine bouncing the rev limiter between shifts.

 

well last time(seems like) I spun tires more when powershifting. Or whats the deal with double clutching? is it better?
Faster,better,worse'r-nevertheless I'm staying with the old, let go of gas and shift fast, method.

 

Lol dude was making a joke Fast & Furious reference. Double clutching is really only used when downshifting, and really only if your synchros aren't working properly. It's never used for upshifting except for heavy duty transmissions with straight cut (instead of helical cut) gears.

 

Hell yea that quote never made sense to be in that movie, sounded like they was all granny shifting lol

Honestly, I can admit I'm extremly hard on my tranny and have powershifted my cars since I started to drive. I have had no issues except with my old 91 si tranny, that's was before I learned the effects of not using honda mtf

 

can a poor tune cause the motor to choke at the high rpm with load?

 

Belive if its running lean it will, which can blow your engine also

 

Please explain a lill more bout the efects of not using honda mtf. I just putt on a gsr trans with 1-4gsr and ls 5th with LSD and putt in the old honda mtf to flush out anything that migh be in there. What trans fuid shuld i run. Talked to a guy on here and he said valvoline 10w30 is good butt thats for engines..? Any ideas would be great.
Thanks

 

I would only recommend using honda mtf

Keeps your from crappin out syncs
Also believe it does something to the running temp of the tranny but not sure

 

You joined on 01-03-2011 and already have close to 200 posts. What up with that.
What do you mean by crapping out syncros.

 

I got a lot to say I guess, I've been on much longer before a couple weeks ago tho lol

Honda mtfs lubricating properties make it perfect for just enough but not too much lubrication of the synchros, which is usually the failing part of honda trans

Same goes for autos, if you ever ridden in a auto accord or teg that has dextron in it, they shift like your grandmother trying to learn stick at 90yo

 

Well congrats on ure 200th post.

Ima be running valvoline 10w30 in my trans after i flush it out with some used mtf.

 

I hope you realize what you just posted.

"I would only recommend using honda mtf

and then you say

"Honda mtfs lubricating properties make it perfect for just enough but not too much lubrication of the synchros, which is usually the failing part of honda trans"

Is it me or uh yeah. I see ure posts in almost every tread posible here on HT.

 

What's wrong with what I said?

I don't pay attention to that post number, got other useernames n stuff keep forgetting passwords

 

Do not use motor oil in your transmission. It's okay in a pinch, but motor oil doesn't contain the necessary friction modifiers for best synchronizer operation. Whatever you do, DO NOT use synthetic motor oil. The purpose of synthetic motor oil - to reduce friction as much as possible - means the synchros have to work even harder when you shift. Gear synchros require a certain amount of friction to operate properly, hence the friction modifiers in MTF.

Now I have heard that the new(er) formulation of Honda MTF is very good. Tons of people use it with great success.

Another good option is GM Synchromesh fluid, the Friction Modified version, if you can find it. I have been using GM SM FM in my GS-R for nearly 150K miles, changed about every 25K miles or so. I'm just a couple months away from 300K miles on my GS-R, on the original engine and transmission with all original internals, and it still shifts smooth as buttah

Now that's not to say it wouldn't have gotten this far using Honda MTF. I can't say that for sure. All I know is that GM SM FM is a really great transmission fluid for Honda manual transmissions. I have enough in my garage to last a couple more years, and then I'll probably switch back to Honda MTF if I still have the car by then.

I would not recommend going with the Pennzoil version of Synchromesh. It is NOT the same as GM SM Friction Modified, and I can't guarantee good or bad results.

 

You have a PM

 

OK tranny is legit, its only got 60K from 2001 LS. no grinds or popouts, very solid. I have driven many hondas, and this is by far one of the cleanest trannys ive had.... just fyi... seems as if the power just shuts off, I dont know why. just as if I took the key out of the ignition. then it came back... it happens very fast, and I tried to pay attention to all of the symptoms... it is only when I really pop the clutch hard (6 puck unsprung)

 

why the ef do u have a 6 puck unsprung on a stock engine..WWHHYYY...on an semmi sock engine. Ure trans is so hatting you right now. I lost a gsr rans to a act stage 4 unsprung 4 puck clutch because when i bough my teg. The previous owner installed one in it on a stock teg. Because of it. TRans ws winning like crazzy. Do youre self a favor and get an exedy OE replacemt or n stage 1.

 

power just shuts off cause its an ls tranny they have longer gear ratios then gsr and b16 tranny
