Manuel transmission will fit on my 01 insight

[toctoc1980]

I hate my transmission on my 2001 insight
I had replace the 1&2 sincro 30 000km ago and its already gone. To shift in 2 i need to double clucth and my wife cant drive it because of that.

I dont like also the diference of ratio betwen the 1 and the 2 gears.

So im searching if i can do a swap with a other honda.
Anyone know if a honda fit, honda civic hybride or the new 6 speed crz tranny will fit on the electric motor housing?

No one has done any modifications or swaps along the lines you are mentioning ASFAIK.

If your synchro was repaired properly the first time you are very unlucky for it to fail again in so short a period.

Who did the repair? Did it have a warranty. Did they replace all the relevant parts and the input bearing at same time? Correct oil?

Perhaps just buy a scondhand transmission.

I hate to suggest driving style, but is someone changing gear without the clutch?

Im sure the synchro was repaired properly. Its a friend who works with honda since long time and he is spécialised in honda transmission modification.

Before having my insight i had a crx with b18c type r and the same guy modify my tranny with a RS 5th gear and a LSD. I Put more thant 100 000km before someone stole it without any probleme. Also put it arround 10-12 time on the track.

So the tranny has been repaired properly. But its surely my driving style who is not good for a insight. I'ts hard to me to wait for rev matching when i shift first to second gear. With the electic motor who is like a 60kbs flywheel and the BIG BIG diference of ratio between this 2 gears, its look like 1 hours to me what i need to wait for shifting properly. So the syncro is uses faster.

If i can found an shorther gear for the second thats can be fantastic also.

I too am wondering if we have any other options. It doesn't seem that there are many parts available for this transmission. This is a real problem when slowing down to take a turn and you can't put it in second gear. Anyone out there with any better ideas?

Well, 1st is pretty tall, but if you are working the clutch and shifter correctly, synchros should last a long time. The ones on our trannys are pretty light duty, in part because of Honda's obsession to keep everything light weight and our cars having limited power.

There is not a long "wait" between the 1st to 2nd shift, but just be smooth. You are talking fractions of a second differene to do it right.

You might try adjusting your driving style. Shift out of 1st early, and then the rev matching between 1st and 2nd will be easier, since the spread on engine speed will be less. Shifting at say 2200 rpm should land you around 1700 in 2nd (I have checked, just estimating). That is a small difference in revs and the synchros won't get much of a workout.

Most synchro wear is on downshifts, not upshifts.

Personally with this many people having issues with the 1/2 gear syncro's (including myself) there is no other answer except that it is just a BAD design. I've driven stick long enough to be able to deal with double clutching and trying to speed match engine and second gear when down shifting but I don't think my wife or daughter will ever drive this car because of this issue.

Either a bad design, or some jerk was downshifting into 2nd at 50mph without revmatching all the time.

It hadn't occurred to me that I shift around 2000rpm for economy, almost never rev it out to redline before shifting or do hard downshifts into 2nd from speed. If I wanted to do that I'd have bought an S2000, a Miata, a Boxster, or something like that. A DSG transmission would be even better: faster shifts. The Insight MT was probably built with an eye to minimal internal frictional losses, and that may make it less resistant to jamming shifts.

Even though it LOOKS like a sports car, the Insight-I was designed for max fuel economy, and people who insist on tossing it around like a sports car may run into various problems. Just as someone offroading in a Porsche (except for the Porsche SUV's) would run into serious problems from low ground clearance. Would that make the Porsche a BAD design??

I'm also curious about this. I would love to get rid of this giant terribly geared piece of peanut brittle honda called a manual transmission.

It is an engineering failure. In their insane attempt to cut weight at all costs they made their already super small transmission smaller by making parts in the transmission smaller. One of those parts they decided to shrink was the synchros. Brilliant! The only real wear component in the transmission and you make it even smaller. To get worn out faster. GREAT! And you can say "well just find a used one". Yeah right. Cause these cars are just all over junk yards...

I would love to but a d16z6 transmission from a civic of most years. Or even better an integra type r close ratio 5 speed with a limited slip. This transmission is in all honesty one of the worst transmissions i have ever come across in all of my car travels. I'm a mechanic. And i have worked on a lot of cars. VW's are the only thing that comes close to this in terms of longevity. The only plus there is the parts are everywhere and the same transmissions were used for over 15 years in some cases.

Know any other production cars that can average 80-100+ mpg??

They were probably more concerned about minimizing frictional losses in the transmission than with weight, though weight was probably a secondary concern.

Rev-matching or better yet double clutching on downshifts minimizes synchro wear and is a good idea on any transmission. As is not jamming upshifts by rushing and/or keeping the gas pedal down.

Lots of people here, including me, aren't having problems with the Insight's MT. Which suggests that the problem is not with the transmission.

I've been driving almost exclusively MT's for almost 50 years now. Early on, I got the message about taking it easy on MT's after jamming 4th-to-2nd downshifts in my Triumph blew out the output shaft oil seal.
