I usually post on the CL side but wanted to check over with the TL guys as I know some of you have down a swap to a manual transmission and I really need help from someone that understands the workings of the transmission internally. If anyone has some time today or this weekend that truly understands the inner workings of a manual transmission, I would sure love to talk and discuss symptoms and try to wrap my head around what is happening inside of my gearbox. [Please send a PM if thats cool.]

This transmission has essentially been rebuilt 4 times in a little over a month. I am so frustrated and would feel better if I have an idea wtf is happening.

I haven't really covered all my symptoms in a thread, but the most recent is discussed here: https://acurazine.com/forums/2g-cl-2001-2003-50/newly-rebuild-6-speed-proper-bed-procedure-832713/

Many thanks.

My buddy Teo Freeatlast is currently doing a 6spd sway right now.

He might know

Look for his thread on the 2G TL side

try GM syncromesh modified friction fluid.

I can hardly think of any aftermarket components that are better than the Honda-contractor ones used by Honda. If so, Honda would have used them to "band-aid" it's crappy 2G TL/CL trannies.

you actually believe that?
honda and most makers use what they can buy in bulk for cheapEST!!
The aftermarket exist for those wanting `better than stock`

As to fixing the gen2 trans- its not just installing better clutch plates
there are issues of internal room and the pathways are not up to the task

How are they supposed to fix that with a part? other than the post 2005 case design change with better oil flow

Bought the car with about 95k knowing it had been rebuilt but only because the seller provided receipts in excess of $4k from an Acura dealership.

I started getting some grind in 3rd gear. Learned of the 3rd gear synchro service bulletin. Tried some other fluid to no avail. Knew I needed to get it rebuilt. Especially after just avoiding 3rd gear for so long and the problem getting worse.

The shop opened the transmission and showed me many worn bearings, etc. They ordered a whole new gear set, flywheel, clutch, throwout bearings, etc.

1st rebuild (he actually did it twice) I get it back and it grinds some shifting into 3rd and 4th. Owner takes responsibility and said he had put on some rings onto the new gear set not realizing they were already on the new set. And that when he pulled it to remove them it must have already been damaged

2nd time: Get the new gear set installed and get back the car and I notice it grind on DOWNSHIFTS to 4th. He said the whole thing has to come back out.

3rd time: He brought in a specialist from another shop that only deals with manual transmissions. They redid it again and said the there was some spacing issues and that the rebuilder had to correctly shim some and adjust some spacing. I was warned that small grinding was ok as the gears(?) needed to seat themselves and that I should give it a week or two and to just drive the car normally. I did as instructed and tried to let the synchros "bed-in".

• Upshifts to 3rd... ok
• Upshifts to 4th... sometimes ok, sometimes small grind, sometimes felt like it was a little loose holding and I had to give a bit of a concerted effort to make sure i got it all the way in.
• Downshifts to 3rd... sometimes ok, sometimes slight grind
• Downshifts to 4th... sometimes ok, sometimes slight grind

After about 12 days of this behavior, I suddenly popped out of 4th gear and figured I didn't shift it all the way in. I tried again and it seemed ok. Then it popped out again and now I don't have 4th at all. If I try to get it to hold it grinds and pops back out.

On a side note. Since the 4th thing happened. If I drive the car normally without 4th gear, I hear no more grinding, and I can even downshift through all the gears grind-free, even 4th gear!

There it is in a nutshell Sorry so lengthy but its better than my pages of notes


OK I will and thanks Flipster!

Ok, thanks justnspace!

Just to be clear. Although I put in new aftermarket shift bushings, I did opt to stay stock here on all the internals. So everything that has been ordered has been from Acura. In this case I'm happy I did too, because I was going to go with a lightweight flywheel, but now the builder can't blame anything aftermarket.

Still sounds like a rebuild issue. Syncros or spacing isnt right or possibly a damaged syncro?
By chance what fluid did they put in it.

CLSspeedx

Honda MT fluid at least the first two times because I saw the bottles and the item on the paperwork. This last time he said something about them reusing the fluid . I don't know if it is a line of bull or not, but that is why they said they would order more fluid and change it Monday.

CLSspeedx

New fluid in. Popped right back out of 4th. Now he wants the car a whole day to "check some things". Well as far as I'm concerned a transmission issue like this is internal and he has had it open 4 times. Have I been patient enough to consider it time to move on? Either to another Aamco I can trust, or to cancel the charge and move to another shop entirely?

fsttyms1

You already payed him. Make him fix it. I wouldnt go as far as to say you trus aamco, they arent really a good place either.

CLSspeedx

I agree. The problem now is I firmly believe he is not capable to fixing it. He already brought in a Manual Transmission "expert" this last time. Even the corporate Aamco customer service rep advised me I might to put a dispute in with AmEx after I went over all the details from my pages of notes.

Also, I spoke with another Aamco about exercising my warranty, and he warned me that the process is lengthy and they have to run everything by this shop and they will often say "well let us order this" or "send it here we can do that", etc.
