Upgrading to a 5speed.

[WSOPgold2012]

What are the benefits to this upgrade. Also, aprox cost of new tranny + tcase?

Thanks

Please search. This is covered heavily. Look up h55f

Flat land or down hill lower rpm’s, uphill nothing
My 4BT can do 65 mph in 5th and still only runs 1850 rpm’s

Hardly get abv 2500rpms in my rig...never in 4th. But...hvnt driven in a while, my memory is a lil faded.

If you don't do a lot of wheeling that requires low range, you can put 33x10.5s on your truck and get a 'rubber overdrive' that will lower highway RPMs a bit. The cost of a transmission ($2700 or so) and labor (and an xfer case rebuild) can put the price easily at $5K-6+, if shop does it. Maybe less if your truck is mid-'85-1987 mfg.

My 2F and 4 spd ran at 2500 rpm’s at 55 mph on 32” tires in 4th.

Mine runs at about that (again...memory may b off) on 33s at 70mph+... I'll have to keep an eye on this. But...2500 seems to be about right

Appreciate the time for this reply....I currently do ZERO off roading. May/may not change in future as I have lotta Colorado to explore.

Best answer evah!

I went from stock tire size to 31”’s and the rubber OD was a great way to drop highway rpms and spend only about $600. Sure I’ll have to replace them in 50000 miles but that could be 10 years for me

The advantage of an H55f is then being able to impress chicks with your sweet Land Cruiser transmission.

I'd need alot more than a new transmission....

 

[Seth S]

And a new H55f is all clean and shiny. It would allow you to swap to 33’s and swap to some 62 diffs, have a low first gear and an overdrive 5th.

I’d love to have 5th for long stints on the highway just to drop the revs more as the 2f seems happiest the slower it spins.

I have 33s already....

@WSOPgold2012 not trying to be flippant...but don’t short change this statement. There is a lot of merit behind this thought.

 

[HemiAlex]

Depends on what you need. The transmission is $2600+\-

My swap was much more than that with a t case rebuild, and all the overdue might as well upkeep I did while I was there. The 5 speed cost me all in was more than the initial purchase price of my truck and it was completely worth it.

what year is your 60 series? year will determine parts costs
