Difficulty shifting into 1st, 2nd after 30 minso driving

[Cali Cruse]

It seems that after 30 mins of mixed driving, it gets difficult to shift into 1, 2 and reverse. Any ideas? Need a Trans fluid flush?

auto or manual?  

 

when you get a spare moment, try to add your truck's details into your signature.

It's a 4.0 inline 6 4x4 manual. Pioneer. Pics will be coming shortly. And I'll update the signature. Thanks!

Which year and transmission?  When was the last time you did a fluid change?

It's 91 manual and it's got to be Aisin, right? I just got the truck...had an alignment done, fixed the wobbly brake pedal, did an oil change, spark plug change and tomorrow getting the transmission fluid check and flush...also the coolant. I'm hoping this is down to the transmission fluid.

Bleed the clutch.

But OP, don't just bleed it looking for bubbles.  It's time to replace your fluid, followed by a proper bleeding.   

 

Clutch fluid is hydrophobic.  Over time, moisture diffuses into the fluid through the various rubber hoses and seals.  As the moisture content of your old clutch fluid increases, the boiling point of the fluid goes down.  In short,  boiling is bad.  And it means your clutch won't work as well after the system heats up.

True. This is why I use DOT-5 silicone brake fluid in my clutch as well as in the brakes. It doesn't absorb water.

 Hydrophobic literally means “the fear of water”. Like an animal who has rabies. LOL.

 

Hygroscopic is what brake fluid is. It's one of the most overlooked fluids when it comes to maintenance.
