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

[mmcdonald]

MY tranny acts totally normally in manumatic if I put it in 5th. It upshifts normally, AND it downshifts normally, AND I have 5th gear.

It DOES kick down when I get into it, most recently kicking down at 70mph to zoom me to 80mph with NO lag.

No Lag.

No Lag.

No Lag.

Normal up and down shifts.

Did I mention no lag?

isn't stay in Sport Mode waste more gas? -_-;;
i don't have much money to pay for my stupid gas now~
it's 2.79 in my area...

There is no "sport mode." The ONLY thing the manumatic does is limit the shift points IF you manually shift up from 1st. If you put it in 5th and drive normally, then it is EXACTLY the same as Drive, except no lag.

I have been driving this way and there is no difference in my gas mileage.

At last I am getting the car I am paying for... or something like that.

No lag.

I agree, driving in manumatic in fifth gear seems the same as in full Auto.

I drove with my car in manumatic all day and the shifts do feel different. More crisp and better throttle response for the most part. I'll pay more attention now as I am often in manumatic for merging, passing, etc., but never pay much attention to the automatic shifts.

[mmcdonald]

I agree TW85, more crisp, and better throttle response was the whole idea.

This morning I watched mpg, and it was the same on the commute. About 28mpg combined highway/city (mostly highway.) So I don't think there is any difference except the loss of the lag.

I think Toyo must have really softened the throttle response in drive, especially for the SLE drivers
and then crisped it up for the Sport drivers in manumatic , but didn't do a good job of it until the second rev during the 2004 model year run.

I'll second that. Tried yesterday, feels a lot better.

I spent 30 minutes on the road last night testing this theory. I spent time in both modes (automatic and manumatic 5) "punching it" at various speeds. After exhaustive research, my conclusion is that there is absolutely NO difference. The lag was still there, the shift points were the same. I tried really hard to notice a difference, but there wasn't any.

For those that are saying they notice a difference, perhaps you're hoping to feel a difference? Just a thought.

Anyway, that's my two cents worth.

SO what you've found is the only way to not have lag is to manually downshift to third while in manumatic mode when punching it? I don't see how you would have any lag doing that. Does that get rid of lag for you?

I am just as skeptical as you are. I'm going for a 40 mile round trip drive in a few minutes and will have the car in manumatic the entire drive. Hoping to continue having the same crisp shifts I had yesterday.

One thought that popped into my head: Is it possible that the car learns two shifting patterns, one for manumatic and another for automatic? Normally when I shift the car manually, I am accelerating very quickly because of cars approaching behind me. I'm wondering if the car learns my shift points and then applies them to automatic shifting in manumatic mode. Is that confusing? LOL

After trying "manumatic 5," I would say that at high speed, the lag is still there. The lag is also there during low speed cruising but not as long/noticeable as the lag when driving in D.

[mmcdonald]

Well, I don't know what to think with these responses. I know that I now have a much more responsive throttle. I have been driving for 30 years, and I have had cars with lag, and without. Before it was like a 1968 Dodge 318 2bbl with a bad carb, and now it is like a normal car.

I HOPE it is not relearning its bad habits as I continue to drive in Manumatic. That would be like flowers for Algernon.

(Okay, now which one of you geeks got that literary reference?!)

I really doubt the car is able to "learn" any driving habits. If it's able to "learn" anything at all, the lag shouldn't be there after all those miles we have put in the car.

This evening, experienced another dangerous moment while in "manumatic 5" mode. Based on my experience, I think the lag is most horrible when you are trying to move to the adjacent lane real fast and also "gunning" the car.
