Quick Cure for Throttle Lag - No Cost, DIY when you drive

[mmcdonald]

Okay, I saw some dancing around this cure for the throttle lag in another thread, but the members were not clear on how the manumatic mode works.

CURE: Put the transmission in Manumatic mode and upshift to 5, leave it alone, and drive. That's all there is to it.

When you shift into this mode, the gear selector INDICATES 4. That is in fact the highest gear the transmission will shift into in this default. The transmission will in fact continue to operate normally in Manumatic. If you shift into this mode and then upshift to 5, you now have the transmission operating normally in all its gears. It is your option to use the manual up and down shift if you want, but if you don't, the transmission will shift normally. This is exactly what it does in Drive mode anyway.

Best of all, the lag is GONE in this mode.

This is not a sure cure, since if you put the transmission back into drive, the lag is back, and you have to watch the shift lever to make sure it isn't accidentally knocked into a lower gear indication.

Please remember about manumatic mode: The gear showing on the dash is ONLY THE HIGHEST GEAR the transmission will shift into, it is NOT THE GEAR YOU ARE IN. When you use this mode, you are essentially limiting the shift point to a HIGHER RPM. If you are in first (1 on the dash), for example, the trans will stay in first until you upshift. It will stay in first right up through the rev limiter. If you start off in 5th (5 on the dash), it will shift normally up through the gears starting with 1st until you reach 5th gear, THEN it stays in 5th until the limiter since there is no higher gear.

So put it in Manumatic mode, upshift to 5th, and leave it alone. The lag is magically gone.

Thanks other posters for this cure. It seems you didn't know how the tranny reallly works in this mode and so were only using it for a fix when you were racing in the mid gears.

Thanks mmcdonald. I for sure will give it a try. So based on your explanation, I assume by driving like this (leave it at 5 in Manumatic mode) shouldn' do any damage to the engine/transmission.

True, you won't have to ever upshift in manumatic mode but you have to manually downshift to get more power on demand. Manumatic mode doesn't automatically put you in a lower gear for passing power.

[mmcdonald]

theFlow: Take a look at your owner's manual. I don't believe this will do any harm since the only purpose of the manumatic is to limit the shift point manually - IF the transmission is being held in a lower gear. There are also no warnings about over using the manumatic, except about shift points. Well, the only reason we use the manumatic is to hold the tranny in a lower gear to override those shift points (until now)! Allowing the tranny to shift on its own in manumatic mode is no different than leaving it in drive.

If you put the tranny in drive, and then in Manumatic 5th, I bet you couldn't tell the difference except for the lag.

Slingshot: When you leave it in Manumatic, it shifts up and down normally, including the passing kick-down. If you want to force it down, then just downshift.

slingshot,

When in sportshift, the transmission will upshift and downshift just like when in D. The only difference is you can control the highest gear the transmission shifts to and of course, you can manually shift the gears yourself.

[slingshot]

Manumatic only downshifts if you move the shift knob back. It does not downshift on its own by putting the pedal to the metal like full automatic does (but with a lag sometimes). I think people are getting the wrong impression (and a dangerous one) that they don't have to even move the gear knob to downshift in manumatic. You do have to do SOME work though its not much work at all.

[TW85]

LOL, I can leave my transmission in sportshift mode on 5 and if I hit the throttle at 55 mph, it will downshift (true at any gear, actually). It acts like an automatic transmission if you do not change the gears yourself.

[slingshot]

Sure, if you like going into the red zone. I'd rather shift manually to downshift in manumatic mode between 4,000 and 5,000 rpm.

[TW85]

The engine does not go above redline if the transmission downshifts in sportshift mode. Bottom line is you can leave the transmission in sportshift mode and it will behave like any other automatic transmission UP TO the gear you have selected (assuming you do not shift yourself). It will downshift when needed and upshift when a gear has run out or when cruising speed is reached. Set the transmission for "4" and it will make the 1-2, 2-3, and 3-4 shift as well as the 4-3, 3-2, 2-1, 3-1, and 4-2.

The "manumatic" basically turns off the overdrive and changes your shift points.

It's pretty bad then if the display number stays at 5. That means it can be switching to different gears and you have no clue what gear it is in. I just went for a drive and put it in manumatic set to fifth gear. I noticed my RPM's were lower (1500) than when set to Auto when going about 30-40. Giving it gas to speed up was slower than downshifting so basically leaving it in manumatic and not downshifting is a waste of time if you want good acceleration. You have to downshift to get any responsiveness if in manumatic mode set to fifth gear.

i think we need a manumatic sports shift driver education class for some


and im not talking ike i know all there is to know here heck took me a while to get used to it too

ill tell ya 1 thing 3rd rocks to make ya gogogogo on a hwy on ramp

Oh yeah! Move the lever to the left, nudge it down once, and you're a rocket!

Manumatic does lock out overdrive. As the default it goes into 4th as the highest when you first enter manumatic. However, you can take it up to 5th and then overdrive is not locked out. If you put it in 3rd, then 4th is "locked out."

I haven't noticed any different shift points when in manumatic. Downshifts are the same.

Let's all do tests by driving over the same course and noticing where the shift points are in each mode.

I tell you, though, the car is totally different in this mode, and if your dealer tells you the lag when in drive is "normal," just do a test drive with him with it in manumatic and see what he says then.

Also slingshot, when you are in drive you have no idea what gear its in. Using manumatic as a substitute for drive makes no difference then.

I am also going to test my gas mileage using manumatic exclusively. That will give me long term shift point data.
