I did the fuel pump recall last week, and ever since I got the car back I'm starting to miss shifts into 3rd gear in manual. It's happened about 4 or 5 times now in the last few days. Is anybody else experiencing this issue? I'm not sure if it's a coincidence with the fuel pump change, but I definitely did not have this issue before it was changed.

Cheers,

 

I have not done the fuel pump recall yet.

But this is strange.

 

Mine is getting done next weekend, April 7th. What do you mean it's missing 3rd gear? Going from 2nd to 4th? I'll report back once I have mine done.

 

My bad man, I should of been more specific. So when I shift from 2nd to 3rd it stays in second gear then redlines hard, as I'm expecting it to shift. When I don't take it to redline, mabye around 4 to 5K rpm the shifts seem a bit delayed from 2nd to 3rd too. When I start to keep an eye on it, or reproduce back to back mishaps it doesn't do it. It's like it only happens when I'm not paying attention.

I know if I take it in, it's not going to happen with the technician.

 

Hmmm....Lexus tried to replicate a true manual so it will hit the rev limiter at 7450 rpm when the torque converter is locked up and then keep cutting fuel off intermittently until you shift to 3rd. Mine does the same in all gears from 2nd onwards. I believe, the 1st to 2nd will hit the rev limiter and then automatically shift up from what my observations are.

 

Interesting @05RollaXRS. I wasn't aware of that, but very good to know. When I have the issue it won't get out of 2nd. I finally see it and I let go and she comes down in 2nd gear, rumbling all the way. So I definitely can tell it never left 2nd gear.

 

Yeah, only 1st to 2nd shift up will be automatic after you feel few jerks of the fuel cutoff. 2nd onwards in M mode, when you go past the redline into the rev limiter , it will bounce off the rev limiter cutting fuel off until you shift up. I have driven manuals all my life so I am very used to rev limiters.

 

In the Armytrix vids I posted, he's always tapping out the redline and you hear the exhaust make that 'dat dat dat' sputter. He loves doing that, but apparently not to many cars will do that he said.

I know we keep saying it, but if the F was a manual ...oh my would I be a happy camper. And to take it even further in my dreaming mind, have a way to switch it back to our current transmission method when we are in traffic. Now I'm dreaming. TBH driving a manual wasn't that bad in traffic. I do miss backing up w/ a manual in a parking lot, and giving it a little rev and have everybody kind of turn their heads.

I'm going to keep an eye on the shifting and see where I stand. I was just curious if anybody else was experiencing it too.

 

I haven't had the high pressure fuel pump work done on my car yet. It's scheduled for this Thu.

Now regarding your shifting issue you are describing, the only time I experience what you are reporting is when the car is not fully warmed up. So even when the coolant temp has reached normal (after about less than 5 min) and the engine oil temp has reached normal (after about less than 15 min) sometimes I find the tranny oil temp has not reached normal operating temp and the up shifts under spirited driving will not take place. However, once the tranny oil temp is at normal operating temperature the shifts are bang, bang, bang... Note, depending on the outside temp, I find the tranny can sometimes take up to 20 min to reach maximum performance.

Indeed! I noticed this too. If I put it in Sport+ and shift moderately when she's cold, the shifts are definitely delayed. And this makes total sense, so now I always have it in Normal until shes' fully warmed up and I can see my fluids are in the middle, and my redline is opened up. Then I will switch it to Sport+ mode. She definitely takes a long time to warm up in the winter, and on those cold mornings. This sucks sometimes as I need a little get up and go sometimes when I merge on the freeway, so I try to warm her up better on those cold days. Regarding the tranny, I can see the same that it would take longer.

 

I bet this was discussed in another thread, but what stood out for you with the RR tune after you did it? Were the shifts any better? Car feels more aggressive?

I'm really thinking about doing it, I was just afraid I would mess with the warranty. I know it would, but more so worried that something would go wrong right after I did the mod.

 

Just came from a 6 speed manual, and don't miss rowing through the gears at all. Does seem kinda strange now with a automatic, since my left leg and right arm, act like they should be doing something every time the car starts moving.

 

 

Just curious, are you using the stick or the paddles to shift?
