Upgrade options for Toyota Land Cruiser transmission

I've been having some issues with my transmission on my Toyota Land Cruiser and I'm wondering what upgrade options are available. Any advice on which one to choose?

You can upgrade to a manual transmission for a more hands-on and responsive driving experience.

Another option is to upgrade to a stronger and more durable automatic transmission for better off-roading capabilities.

Consider investing in a high-quality transmission cooler to prevent any potential overheating issues.

Don't forget to regularly maintain and service your transmission to ensure it's functioning at its best.
