I found a 2nd gen today with 30k miles on a rebuilt V6. Altogether the T4R has 260k. It is the original 5sp trans, owner "says" he has changed the fluids regularly...but who knows. My question is, whats the avg life expectancy of a 5sp trans from a 91 model? So far, this is the straightest body I have seen in an early 2nd gen. Forgot to add it is 4WD.
5sp trans life?

Hard to say, you would have to feel it out, like you can kill them by grinding gears and really wearing the synchro's out but that transmission in there was used in from 85-2000 in the 4runner alone (or whenever the v6 was put in the 4runner). The tranny should be good for atleast a half million miles.

Your trans should last for at least 400,000 miles. Mine has 308,000 miles on it and on occasion it will pop out of 1st, but I think that it is more my issue then the trucks. The only problem I have heard is that the shift forks are cast aluminum and can break if it was shifted hard, but I haven't ever seen the problem with my own eyes. I think you got yourself a deal.

You should replace your shifter seat bushing, that sounds like your issue. 4Runners.org - Changing Your Shift Lever Bushing
The transmission is a R150F in the writeup. It's a $5 part.

Listen for whirring or grinding in the transmission.
If it has to be held in gear, or pops out of any gear when you let off the gas, that's generally bad.
Otherwise manual transmissions are very reliable with proper maintenance. If the oil's been maintained in the transmission, and the clutch is in good shape, there's not a lot to worry about.
Auto transmissions have a lot more complication to their workings, that's where you hear of common transmission problems over 200k.

Shifts rough in cold weather
I'm a little off topic, but this is related to manual transmission. My '88 22re clutch feels tight and shifts great when the truck is warm. But on cold mornings it is a little tough to get into gear, especially second. It does shift when cold without clunking, whirring, or any other noise, but it's just a little stubborn to seat into second gear. When it's warm, it shifts very smooth. Any idea what this means?
Thanks!

My 98 does the same thing, I think it's an issue with the clutch not being fully engaged.
I have not really investigated it though.

You really can't put a number on it, a lot depends on how it's been driven thru-out it's life. Changing fluids is very important but isn't a total answer. I've seen many go out at the 150K mark. The L52 in the 83's was a particular POS.
So as the saying goes, Your Mileage May Vary.
