batesy Posted December 23, 2015 Report Share Posted December 23, 2015 I can't find the Ratsun forum thread for morons so I'm just gonna embarrass my stupid dumbass here. So... I put a 32/36 weber on my 180b (610). Lots of stuffing around later -- carb off, carb on again (I swear I was pulling off more times than a 14 year old.) -- but finally I get it running after fixing air leaks. Got left with lots of disconnected hoses hanging from old carb and filter assembly. So, remove a hose, block a hose, replace a hose. All good. Go for drive. All good. Brmm brmm. "Yo... grandma, look at me. Cool dad in orange Datsun. Wanna ride?" Not so fast... more vacuum issues. More hose replacing. Pointless though. Like, literally, POINT-less. Check points. Only electrics part in the whole car that hasn't been replaced. So, file points. Bingo. Runs perfect. But suddenly the auto box doesn't want to change from 2nd to 3rd. What the fuck?! Lift hood. Gotta be vacuum line for auto. Look at hoses. Oh, there we go... dumbass has blocked an auto vacuum line. Goddamn it, Dad was right ... Passion fingers ... I fuck everything I touch. So... Unblock hose. Leave line hanging in the air. Go for drive. No find 3rd. You motherfuckerererer. So here's a multiple choice question... Has my stupidity fucked: A vacuum modulator? An auto gearbox? My right to be a member on Ratsun? Additional info: - Auto was fine yesterday. Even with hoses hanging in the breeze. - Replaced fuel hose. - Replaced dizzy vacuum advance hose. - Blocked a small hose from manifold. Forgot where it ran to. Filter box, I think. - Removed rocker cover breather to air box hose. - Replaced hose from engine block breather to intake manifold. - Filed points. - Timing is fine. (Note to Hainz: I'm not watching your fucking videos again!) - Haven't check transmission fluid level yet but only driven 100miles since last filled. Will check tomorrow morning. - Sprayed carby cleaner around like a kid pissing in the breeze. - Revved fuck out of engine. - Went for drive after that and... no can change into 3rd gear. First fine. Second fine. 1 Quote Link to comment
wayno Posted December 23, 2015 Report Share Posted December 23, 2015 On all the automatics I have, the vacuum line going to the transmission connects to the intake manifold, not the carb, straight to the intake manifold. Quote Link to comment
datzenmike Posted December 23, 2015 Report Share Posted December 23, 2015 So... Unblock hose. Leave line hanging in the air. Sorry, just found this. That hose is supposed to send a vacuum signal to the modulator valve. Vacuum is an indication of engine load. High vacuum... idle, light throttle or deceleration. Low vacuum heavy acceleration. From this vacuum signal the transmission knows when to up shift or hold in gear longer. The little hose near the back of the engine near the intake (usually) connects to the fitting for the large hose to the brake booster. Finger pointing to metal tube that goes to small hose the goes to fitting on intake just behind it. Quote Link to comment
batesy Posted December 23, 2015 Author Report Share Posted December 23, 2015 Thanks guys. Your input is very much appreciated. @Wayno: You're right, The one I plugged was the air filter one. That's why I thought it would be okay to block. I wasn't certain though ... I'm not very smart ... but I can lift heavy things. No, wait... I can't even do that. @Mike: I think you are on the money. I only checked that hose visually. It already had a kink in it but I must have bumped it a dozen times with my hand and a screwdriver. Just checked it then and could feel the split open up. I'll take it out for a spin once the neighbours wake up and see if that fixes it. Definitely going to be sucking air there though!! 1 Quote Link to comment
datzenmike Posted December 23, 2015 Report Share Posted December 23, 2015 That hose needs to be replaced. Right now it is a vacuum leak which not only will foul up the transmission but the engine won't run right either. Quote Link to comment

batesy Posted December 26, 2015 Author Report Share Posted December 26, 2015 I did vedio cause I got tired of writing on how to do timming chains. Believe it or not, I didn't even know about the timing notch until I watched your vids! Even though i'd built three L18s as a young dude... With the help of a Haynes manual. And mates. No wonder I could never get the fuckers to run right. Nailed this L20 though. Still not going to give you too much credit though. What with you being American and all. ;) Quote Link to comment
