Would suggest have it stripped down now why you still have some use left in clutch you dont want to wait until it locks up completely as may cause more damage

SOURCE: truck wont go into 1st gear until truck warms up.

1989? When was the last time the Transmission was drained and new Transmission Fluid (oil) put in?
This Fluid (oil) loses viscosity and get particles in it causing additional loss in viscosity. I would go to even having the transmission drained and FLUSHED (cleaned) and new Fluid (oil) put in. Recheck the operation.
Boyles and Charles Laws are applicable here: (P*V)/T. Heat causes the Fluid to Heat and Expand (in molecules) but because of the limited sealed volume (transmission case) this increases Pressure allowing the smoother shifting and placement into gears.
Change the Transmission Fluid (oil) and have the Transmission Flushed (cleaning the insides) and your problem should go away.
Let me know if this helped, or if you have any additional information or questions. Feel free to contact me at!

Why do my truck idles so loud the first 2 minutes or so when i start driving?

This is likely the hydraulic fan clutch behind the radiator. Is the RPM high also? If not it's the fan clutch. It is normal for the fan clutch to stay locked until it warms up, a few minutes.

My transmission shifts really good but when im in overdrive driving a steady 60 its slips just a little and slips back, continues till its hot and quits no more slipping

Torque converter lock up clutch is slipping, not good, Its not that it quits slipping when warm, it quits WORKING when warm and is not even trying to lock up any more. Need to have this repaired right away or severe damage will result. Depending on what year it is depends on what is needed for repair. Up until like 2000 it requires the valve be modified and torque converter replaced, after that its seals and torque converter. Any competent trans shop should be able to repair easily.

98 GMC , Reverse slips

Hi there.This is a common problem with these trans.Its the forward clutches that good bad.First and reverse are together in the same pack The reason it slips when its warmed up is that the fluid is thicker and wont slip by the clutches until it is warmed up.A good way to check this is to look at the dip stick and if it has blackish gray cooler stuff on it it is for sure the clutches.Also if your at a stand still with the truck and in drive if you punch the gas does the rpms race up.The a good indication the the trans is going bad.I hope this helps you and Have A Great Day.

1991 Isuzu 4X4 Pickup 3.1 V6 won't warm start plus shudder in low

Your flywheel sound like it has hot spots on it, making the clutch chatter. You might need to pull the flywheel off and get it re-surface. This is like turning your rotor, or brake drum. If you pull the flywheel, you will see discolor spots on your flywheel. This is called hot spots, and will make the clutch slip.

On the other problem, have you changed to fuel filter and fuel pump. It almost sound like your running out of fuel????
