i agree Automatic trannies suck the big one. I added the Lucas stuff and it actually felt like it helped a little bit. The fluid was at a good level before i put the lucas stuff in there. The only problem was the tranny additive was 2x thicker then 90w gear oil and wasn't able to go down the filler tube too well so i haven't been able to get a reading on it. I didn't overfill the tranny, i pumped out about 400mL and put in about the same of the tranny additive. ( the bottle said 12 fl. oz for compact and subcompact automatics which is around 400mL.) I had always wondered why they didn't us 0 or 5 weight oil for AT's but realized that ATF has properties to help the clutches engage instead of total lubrication.



Also, i have found a manual tranny for 200 with the clutch master cylinder. Haven't asked about the bell housing or anything yet. Anyways, is there any way i can check the condition of the tranny without it being bolted up to an engine? The guy lives really close to me so its not like a craigslist scam or anything, i just wanna make sure i don't throw money into this thing if im gonna need a complete rebuild on it. The guy said it was in proper working condition. I would love to trust his word but you know how it is with people these days.

The tranny breaks down lengthwise in three pieces, you still won't be able to see into the gears or syncros but you can check the linkage for play or bends.

Crap that's the fd trans. I need to stop jumping around between the different sub boards, I'm getting mixed up lol

lol its all good. Say though worst case scenario the whole thing needs to be rebuilt. I'm pretty mechanically inclined and i have the manual to walk me through it the only thing i would need are the extra tools necessary to do said rebuild. How much would it cost me around, do you know?

I can't remember how much I got quoted, I ended up saying screw it and got a jdm trans for my fd. The trans shop said it would be over 2500 in parts alone to restore the original oem trans. Snagged a jdm trans for 250 instead had them look at it and they said it was in perfect condition so they only charged me an inspection fee. The original oem trans seemed to shift ok to me except for the fifth gear synchro.

Start watching for a parts car with a manual transmission. You can upgrade to a 5 speed for much, much less than you could rebuild an auto tranny. Then you'll also have all the spare parts you're ever likely to need. https://www.nopistons.com/forums/pub...IR#>/smile.gif

oh ok thanks. i might just do that, inspect it myself to make sure its good enough for me then buy it and take it to a shop to get inspected to see if its in any good condition. Or pay for the inspection and have it done before i buy it.
