    Engine shake at shut off

    No didn't remove engine. I'll check the idle cut. nl320what said bad gas.... come to think i'm running out a tank from last fall and it's down under 1/4 now. Didn't give that a thought. The truck sat over the winter with a full tank in the garage. I just swapped the tranny and started driving it again. I'll top it off with premium and see if that makes a difference.

    Engine shake at shut off

    Running original, Hitachi Carb. Not acting like dieseling, just a little stumble/rock when killing the engine.

    Tranny Fluid - Your opinion

    OK, thought I'd let everyone know the results running the "Royal Purple 01300 Max Gear Ultra-Tough High Performance Synthetic Gear Oil 75W-90" in my 5- speed tranny. It's only been a week but the tranny shifts (Up and Down) smooth as butter, it's quiet. I really thought I'd hear a little bearing wine with the synthetic but not so. ​So far so good, I haven't really hammered it while breaking in a new clutch. I guess I can turn the radio up now, been nervously listening to the tranny. Gonna leave it in and see what happens.

    Engine shake at shut off

    I'm getting a slight engine shake at shut off. Just swapped the tranny, wondering if I weakened a motor mount ? I don't think I have a broken motor mount, drives great but it just started this after the swap. Could it be something else ?

    620 Tranny swap

    5-Speed finally in. Wanted to show the difference in the Speed Pinions. Original Blue from 5-Speed (280-ZX) Original Black/Red 28 tooth from 4- Speed New Silver/Red - 28 tooth The 4- speed Red would not fit all the way in turned opposite (180). Comparing the two Red- original to new 28 tooth, you can see there is a difference in the angle of the teeth. The new pinion fit easily in and is speedometer is right on. Center Bearing Position 5- Speed installed

    Speedometer Cable question

    Can the inner cable be removed at the transmission to lubricate the speedometer cable or does it have to be removed at the speedometer ?

    Tranny Fluid - Your opinion

    I'm going to try this synthetic oil. Hope it work's as good as your GM Delco Friction Modified Synchromesh Transmission Oil. Royal Purple 01300 Max Gear Ultra-Tough High Performance Synthetic Gear Oil 75W-90 Max Gear is recommended for use in truck and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. It is non-corrosive to soft yellow metals (brass, bronze, copper, etc.) and synchronizer safe. Specially designed to extend gear and bearing life, Max Gear provides superior corrosion protection over competing conventional and synthetic gear oils. Royal Purple engineered this ultra-tough, high performance automotive hypoid gear oil to provide maximum protection to heavily loaded gears while maximizing power throughout the drive train. Max Gear outperforms ordinary gear oils by combining the highest quality synthetic oils with Royal Purple’s proprietary Synerlec® additive technology.

    Tranny Fluid - Your opinion

    Here's what the American Petroleum Institute says, what the heck do they know.. API (American Petroleum Institute Classification) GL-4 (Gear Lubricant-4) contains about half the additives of GL-5. Higher concentration of Extreme Pressure additives in GL-5 gear oils may cause the softer metals, such as copper, brass and bronze – which make up the shift synchronizers of a manual transmissions - to suffer premature wear / failure. So, stick with the specified GL-4 classification, in any of your favorite synthetic brands. Mike your fluid, GM Delco Friction Modified Synchromesh Transmission Oil Synchromesh Transmission Fluid, Friction Modified is a synthetic blend manual transmission fluid designed specifically for use in GM manual transmissions. This fluid has excellent lubrication properties that prevent breakdown over time and reduce friction to minimize transmission wear. All-climate fluid that manages temperatures as low as -40 degrees Fahrenheit (-40 degrees Celsius) to as high as 300 degrees Fahrenheit (149 degrees Celsius)

    Tranny Fluid - Your opinion

    Thanks MIke, Good to know, I see the synchromesh fluids and was leery of them because they appeared to be thin like ATF fluid, something I thought would not work well in a gear box. I changed the front seal but I'm going to pull it because it's a single lipped seal. After putting it in I had wished I hadn't. Do you think I should pull the front cover and replace the front seal too ? Did you flush your tranny before changing over to the synthetic ?

    Tranny Fluid - Your opinion

    OK from what I'm seeing the new synthetics are now non-corrosive to yellow metal. Most GL5's are saying that the newer additives now make it safe to use. I did find this video which this trany expert explains this very well. He repairs a munci first so go to 11:30 in the video to where he starts the testing of GL4 and GL5's. https://video.search.yahoo.com/yhs/search;_ylt=AwrC5rK1ygZbsgsAjmo0nIlQ;_ylu=X3oDMTBncGdyMzQ0BHNlYwNzZWFyY2gEdnRpZAM-;_ylc=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--?gprid=nxPKcVuLSRCz2xr28RAR_A&pvid=cq_y2TEwLjFAxMCYWvBZopnlMjA2LgAAAABikVZM&p=GL4+vs+GL5++oil+tests&ei=UTF-8&fr2=p%3As%2Cv%3Av%2Cm%3Asa&fr=yhs-pty-pty_email&hsimp=yhs-pty_email&hspart=pty&type=admk#id=1&vid=861d4400b4b21f93c3c967db7ee2e11a&action=view He likes the DRIVEN GO RACING 80-90

    Ignition on - I got nothing.

    Bad Ground Connection or ground wire.
  12. Getting ready to fill up the 5-speed 71B What's the best oil to use ? Some say ONLY: GL-4 Yellow Metal Safe Some say it doesn't really matter. Some say go synthetic. There are a ton of new oils out there now, viscosity varies a lot. Hoping someone has experimented and can save me guessing.

    Clutch Pilot Bushing/Bearing

    OK, picked up a Dorman and everything fit perfect. I checked the bushings and there was maybe a couple thousands difference in the O.D. One for the books I guess. Here's some pics: Just praying I can get the Tranny back up with the pressure plate in place..
