    I'm new to the board and have recently acquired a '74 Hilux barn find in exchange for my '73 Dodge Dart (sweet trade if you ask me :D)

    It has an 18R-C and L40 4-speed tranny. The main issue I'm having is when I put it in reverse it grinds like hell and then engages, and seems to be my only gear I'm having the issue with. What can be some of the causes of this? I haven't torn into it yet, and the PO said he's adjusted the clutch but he also didn't seem too knowledgeable about... pretty much anything.

    Any insight/advice is much apppreciated!

    Darts are cool but the Hilux is more useful for sure. Welcome to the classic Toyota party.

    Check your clutch fluid reservoir to make sure its got good fluid and make sure your clutch is adjusted properly. I did this to my '74 and it helped. Occasionally it will still complain about going into reverse, but it's more of a clunk than a grind. Sometimes double clutching (pressing the pedal twice then engage) will also help or going to 1st and then head for reverse. Once you get it sorted you should do a fluid change to remove those gear shreds.

    I'll post pics later when I can. I agree MercuryMan... My Dart was a four door slant 6 anyways. Bulletproof but lacking in the cool factor.

    I'll give the double clutch and the 1st to reverse a shot. Any threads on clutch adjustment? This is my first Yota and manual transmission vehicle I've ever owned. I love it though.

    I've considered a 20R swap though. Not now, but maybe later!

    Thanks for the tips! So far so good with forward shifting then going to reverse... no more grinding/clunking!!! Does anyone know the procedure for changing the clutch fluid? Mine's looking a little too dark.

    Basically same as brakes, same fluid too. Empty out as much as you can from the master (to shorten the job) and refill with fresh, open bleed nipple on operating/slave cylinder with hose attached, make sure master cylinder stays full, and proceed to bleed until the fresh is coming out. If you have a vacuum pump you can do this by yourself by just vacuuming the old out while filling with new (much faster), otherwise get a buddy to work the pedal and bleed it clean.

    Where is the slave cylinder located? Like I said... I'm new to this. :confused:

    It's down there on your transmission should have a hard line going into it think it's a ten mm bleed valve or a eight mm can't Rember it's easy to spot just look for the bleed screw on the end of it

    Go to your passenger fender and peer down behind your starter. You will see a rubber hose clamped to your engine that turns into a hydraulic hose and it's leading to the slave. The bleed nipple is on the passenger side of the cylinder. It's easy to get to if you jack up the front of the truck-it may be fairly dirty and caked up if your truck has ever had any leaks, if so spray it with brake cleaner and brush it clean to make it easier.

    EDIT: Sorry scrub i didn't see your post, didn't mean to echo.
