Can confirm. Our '89 has the 5LM60 trans. I kinda hate it too. Shifts pretty good with well over 220k on it but first gear (4.00) is kinda useless unless you're off road and second is too steep to start off in.. It's also really complex, prone to failure and expensive to rebuild. Heard most of them end up junked once they lunch themselves.
