I believe you can't call these rules but there are patterns or whatever you may call 'em. That is, if a verb ends in a certain way, its counterpart is most likely to end in another way or in one of two possible ways. (Sorry for bad English but hopefully you get the idea)
Keep in mind that often you can't determine the (in)transitive counterpart by these and should always look it up on a dictionary but it's a fact that this guideline makes it easier to remember them than plainly memorize this stuff by heart. You can also make lists of what verbs go for which rule and which don't go for any of them and if you review them regularly you should have no troubles with them.
Here they go, int/tr, keep in mind that ~aru doesn't mean ある but any syllable ending in a + る and so on:
~aru/~eru, e.g. 助かる/助ける、決まる/決める etc (note that the ~eru one is always a ru-verb aka 一段）
~u/~eru, e.g. 届く/届ける、つづく/つづける etc
~ru/~su, e.g. 帰る/帰す、残る/残す etc
~reru/~su, e.g. 壊れる/壊す、汚れる/汚す etc
I'm a learner though, please correct me if I lied somewhere
