Upgrades/maintenance while transmission is out??

Howdy Folks,

I'll soon be taking the 4R100 out of my excursion for a pump seal replacement. While the transmission is out, what upgrades or maint items should I be considering? The truck has 105k miles on it and only 40k on the 4R100HD.

Current plans while transmission is out:
Up pipes
Reseal manifolds with gaskets
Tap manifold for EGT (currently post turbo)

Parts
Up Pipes/Collector https://www.riffraffdiesel.com/riffr...roduct-reviews
Turbo V-Band Clamp https://www.riffraffdiesel.com/up-pi...o-clamp-99-07/
Pyro Probe Drill/Tap https://www.riffraffdiesel.com/pyro-...l-and-tap-set/
Exhaust Mani Gasket https://www.riffraffdiesel.com/exhau...et-94-03-7-3l/
Exhaust Mani Bolts https://www.riffraffdiesel.com/exhau...olt-set-94-03/

Any other jobs I should consider doing "While I am at it"? Any other parts I need?

Don't know if the 4r100HD allready has it but triple clutch low stall TC is a good investment.

First, up-pipes are not significantly easier with transmission out. You still need to remove turbo...

I never replace the v-band clamps.

Are your exhaust manifolds leaking?? They almost certainly will if you install exhaust manifold gaskets.

Check out the write-up for how I do up-pipes and turbo mods if you haven’t yet.

If that is a Ford transmission, shouldn’t it be under warranty???

I would recommend plenum inserts, t-bolt clamps to replace worm clamps and upgraded CAC boots.

Also, remove clamps from fuel lines in valley.

You may consider upgrading compressor wheel while turbo is out.

And paint. VHT flameproof (2000*) on carbon steel hot parts. I use rustoleum 2x coverage stuff on everything else. Surface prep is the key to success. Clean (100% grease and oil free) is mandatory. Do not use a wire wheel - this spreads surface contamination and leaves a smooth surface that is harder for paint to bond to.
