Default ITR decelerates sharply in reverse with clutch in

This started the other day, I was backing up and things felt a bit jerky, but I thought nothing of it. Today I backed out again, and when I put the clutch in with the car engaged in reverse it felt like I hit the brakes, the car came to an abrupt halt despite being clutched into neutral. Sticky engagement/disengagement of reverse on the shift pattern as well. Search suggests that it's a shift fork, a 5th gear synchro, or possibly just bad fluid; anyone else experience the weird decelration I'm describing? Car coasts fine with clutch in from first gear going foward.

Thanks in advance for any theories or advice!

my educated guess would be your synchro, i think if it was the fork it'd happen in other gears as well

yes!

I've had that. I'm not a mechanic, but I "think" it has something to do wtih the main shaft being worn and unbalanced which throws other things off. I bet it feels like referse binds in gear sometimes too.

It does seem hesitant in reverse under power, although it's not resisting enough to really bog the engine. Either way looks like I'm going to have to crack it open, bleh.

Sounds like time for a picfest and writeup for some upcoming "Fixing the R" GRM article

Heh, that might be a little too specific for our reader base; What To Do When Your Limited-Edition 5-Year-Old Honda Backs Up Weird: REAL WORLD PEFORMANCE GAINS!

D was the last one in the tranny, he probably left his shirt in there.

Probably, but at least he made sure the shifter bolt was tight!

Err... nevermind.

I was a little bummed we never got to use the plastic washer made from a CVS shopping cart seat after I found the real washer in the middle of the busiest intersection in all of freaking Orlando...

I had the same problem with my transmission. If you put the car in reverse and drive you can feel a drag. The drag is intermittent and varies with the rotation of the wheel. Also, when you leave it in reverse and let it coast with the clutch in (disengaged), the car will come to a stop consistent with the intermittent drag force.

Unfortunately, I don't know the fix as I went and bought a new transmission because I also had problems with popping out of 2nd gear. I was in the middle of a race season so I didn't want to deal with the downtime.

I'll be sure to chime in when I eventually rebuild the trans.

I had that exact problem and it was mostly the shift forks. The synchros were also screwed up, but I'm not sure how related that damage was. Pain in the *** repair too.

I have the same issue. It feels like there is resistance in reverse. Strange thing is all the other gears are fine and it drives fine in 1 through 5? So far I have not had the chance to pull the tranny and look at it. Let me know if you find out what is wrong!

That describes it perfectly. The reverse, plus the 2nd gear popping out, it's got to be related.

Same thing is happening to mine. Car decelerates in reverse and I cant put the car into 2nd gear unless it is from first to second. Been too lazy to pull the tranny and Im wondering if it might be better to buy my friends ITR Tranny.

When the clutch was engaged, was reverse slower than usual? does giving it throttle bring it back or does it bogg? Im asking this because I think I have the same problem, just don't know whats wrong.

There is some resistance with the car in reverse and the clutch engaged (pedal out), but it doesn't override the engine's torque at idle; leaving the car in reverse with no gas allows the car to maintain a constant idle speed in gear.

Those of you who have this problem, how long have you been driving around with it?

A few months, until I replaced it. The problem got progressively worse. Cause unknown.

Might as well upgrade the FD while you are in there if you already havent.

Don't rule out stick brake adjusters on rear wheels. Chock the front wheels, release the e brake, jack up the car and see if the rear wheels turn freeely.

Does the car have a hard time going into 2nd sometimes?

My B16 transmission did the same things you mentioned.

Turned out to be a bad countershaft bearing causing everything to bind up.

One day I guess it wobbled around too much, and some teeth from my countershaft decided to 'liberate' themselves through the bottom of my tranny casing.

Weird you should mention that, just got back from Rally NY and second gear was being reluctant in some cases. Guess I should take the car offline before I frag something good....

FD is already upgraded, but this will be a good opportunity to get that Toda flywheel installed finally and upgrade the clutch.
