Released in 1966, it combined attractive styling, improved suspension, front disc brake availability and the increasingly popular Red Motor engine range. For many enthusiasts, the HR represents the perfect blend of early Holden simplicity and modern usability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Like any vehicle approaching sixty years of age, however, the drivetrain requires careful attention. While Holden&#8217;s transmissions were generally robust and well-suited to Australian conditions, decades of wear, poor maintenance and ageing components have created a number of common problems that owners regularly encounter today.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether your HR Holden is fitted with the standard three-speed manual, the optional four-speed manual or the two-speed Powerglide automatic, understanding these issues can help prevent expensive repairs and improve reliability.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Understanding the HR Holden Transmission Options<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The HR Holden was available with several transmission choices.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Manual Options<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Three-speed column shift manual<\/li>\n\n\n\n<li>Three-speed floor shift manual (some applications)<\/li>\n\n\n\n<li>Four-speed manual (performance and aftermarket conversions)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Automatic Option<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Two-speed Powerglide automatic<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Both the manual and Powerglide transmissions earned reputations for durability, but age has now become the primary source of problems.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Gearbox Oil Leaks<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Oil leaks are one of the most common complaints among HR Holden owners.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Oil spots under vehicle<\/li>\n\n\n\n<li>Gearbox housing covered in oil<\/li>\n\n\n\n<li>Low lubricant levels<\/li>\n\n\n\n<li>Increased gearbox noise<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Common Leak Locations<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Input shaft seal<\/li>\n\n\n\n<li>Output shaft seal<\/li>\n\n\n\n<li>Selector shaft seals<\/li>\n\n\n\n<li>Side cover gasket<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Most leaks are caused by hardened seals and ageing gaskets.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Best Gearbox Seal Kit<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Recommended Product: Permaseal Transmission Gasket and Seal Kit<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Benefits<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Quality replacement materials<\/li>\n\n\n\n<li>Reduces leaks<\/li>\n\n\n\n<li>Suitable for rebuilds<\/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>Oil leak repairs<\/li>\n\n\n\n<li>Transmission servicing<\/li>\n\n\n\n<li>Restoration projects<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Replacing seals early can prevent more serious internal wear.<\/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;Gasket<\/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.
