Released in 1963, it introduced Holden&#8217;s new Red Motor engine range and quickly became one of the company&#8217;s most successful models. While the 149 and 179 cubic inch six-cylinder engines are often the stars of the show, the transmission sitting behind them plays an equally important role in the driving experience.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today, more than sixty years after production ended, many EH Holdens are still running their original gearboxes. While these transmissions were renowned for durability in their day, age, wear and decades of use inevitably create problems that owners eventually need to address.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether your EH is fitted with the standard three-speed manual, the optional four-speed manual, or the popular Hydramatic automatic transmission, understanding the common transmission faults can help you identify issues early and avoid costly repairs.<\/p>\n\n\n<div id=\"fu_ebay_0\"><!-- Presentation: cols = 4, rows = 2, slideshow = Manual, slides = 3, slideId = 0 --><div class=\"fu_ebay_results_container \">\n<h5 class=\"fu_ebay_results_title\" style=\"display: block !important;\">\n<a name=\"fu_slidetop_0\"><\/a><a href=\"https:\/\/www.ebay.com.au\/?mkcid=1&#038;mkrid=705-53470-19255-0&#038;siteid=15&#038;campid=5339152561&#038;customid=5339151688&#038;toolid=10049&#038;mkevt=1\" class=\"fu_ebay\" style=\"display:inline !important;\" rel=\"nofollow\" target=\"_blank\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/australianholden.com\/wp-content\/plugins\/fast-ebay-listings\/US\/Right_Now_108x45.gif?resize=108%2C45&#038;ssl=1\" style=\"border:0;display:block !important;\" width=\"108\" height=\"45\" alt=\"Right Now on eBay\"\/><\/a>&nbsp;Transmission<\/h5>\nLoading&#8230;<\/div>\n<\/div>\n<script>\n<!--\nvar content_fu_ebay_0 = null;\nvar waitForDepends_fu_ebay_0 = setInterval(function () {\n  if (typeof jQuery !== \"undefined\") {\n  if (window.fu_is_bot_useragent !== undefined) {\n    clearInterval(waitForDepends_fu_ebay_0);\n    if (typeof jQuery.ajax == \"undefined\") {\n      console.log(\"Fast eBay Listings: jQuery.ajax missing.

class=\"wp-block-paragraph\">The EH offered several transmission choices depending on model and specification.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Available Gearboxes<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Three-speed manual column shift<\/li>\n\n\n\n<li>Three-speed manual floor shift (dealer conversions common)<\/li>\n\n\n\n<li>Four-speed manual (limited applications)<\/li>\n\n\n\n<li>Two-speed Hydramatic automatic<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The majority of EH Holdens sold were equipped with the three-speed manual transmission.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today, many surviving vehicles have been modified with later Holden gearboxes, but original transmissions remain highly sought after by restorers.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Hard Gear Changes<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most common complaints among EH owners is difficult shifting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Resistance when selecting gears<\/li>\n\n\n\n<li>Crunching during shifts<\/li>\n\n\n\n<li>Stiff gear lever movement<\/li>\n\n\n\n<li>Difficulty selecting first gear<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Common Causes<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Worn synchronisers<\/li>\n\n\n\n<li>Old gearbox oil<\/li>\n\n\n\n<li>Clutch adjustment issues<\/li>\n\n\n\n<li>Worn selector components<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Many owners initially assume the gearbox is failing when the real culprit is clutch adjustment.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Worn Synchronisers<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The synchromesh assemblies are designed to match gear speeds during shifting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After decades of use they inevitably wear.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Gear crunching<\/li>\n\n\n\n<li>Difficulty selecting second gear<\/li>\n\n\n\n<li>Shifting improves at low engine speeds<\/li>\n\n\n\n<li>Grinding noises during downshifts<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Second gear synchronisers are usually the first to show wear.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is particularly common in vehicles that have spent years in stop-start traffic.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Gearbox Noise<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Gearbox noise is another common issue in ageing EH transmissions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Whining noises<\/li>\n\n\n\n<li>Bearing rumble<\/li>\n\n\n\n<li>Noise in specific gears<\/li>\n\n\n\n<li>Vibration through shifter<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Common Causes<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Worn bearings<\/li>\n\n\n\n<li>Gear wear<\/li>\n\n\n\n<li>Low oil levels<\/li>\n\n\n\n<li>Incorrect lubricants<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A noisy gearbox is not always immediately catastrophic but should be investigated.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Best Gear Oil for EH Holdens<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Fresh oil is often the simplest way to improve gearbox performance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Recommended Product: Penrite Manual Gear Oil 40<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Benefits<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Suitable for many older manual transmissions<\/li>\n\n\n\n<li>Excellent wear protection<\/li>\n\n\n\n<li>Smooth shifting characteristics<\/li>\n\n\n\n<li>Designed for classic vehicles<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Best For<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Original manual gearboxes<\/li>\n\n\n\n<li>Restorations<\/li>\n\n\n\n<li>Routine maintenance<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Changing gearbox oil is one of the most overlooked services on classic Holdens.<\/p>\n\n\n<div id=\"fu_ebay_1\"><!-- Presentation: cols = 4, rows = 2, slideshow = Manual,
