Within the next week, I should be installing my new transmission in my '93 Mark. While I have this out, what else should I replace?

I've already purchased:
IACV and gasket.
Transmission cooler.
Rear main seal.

What other parts that wear out, that really necesitate removing the transmission, should I replace at the same time?
 
Get new transmission mounts; preferably poly bushings. Before you thrown the tranny in, do a J-Mod. While you have room, check your oil pan for rust...
 
The stall is really the reason I'm changing the transmission. A heavy duty 2500 stall is going in. And the transmission is being custom built with the fun factor in mind. I completely expect it to feel like an entirely new car once it's installed.

peformance transmission and the custom exhaust last month all within the last month it should really come to life.

others can chime in here,but imho 2500 wont make enugh change for all the work you are doing.

does anyone know what stock stall is?i have seen numbers from 2000 to 2700rpms posted on various sites.

i put in a heavy duty 2200 and it feels stock to me.

maybe i am wrong........

The 2500- will certainly make some difference. But I'm not changing the transmission simply because I want a different t.c. I'm changing the transmission because my old torque converter is fried, the unit has 186k miles on it, and it's days are numbered too.

Everything I've read says, contrary to your numbers, that the stall speed is somewhere in the 1800-2100 range on the Mark VIII.

can anyone confirm this?
 
You might look at doing the Apten cooling mod.

Basically running a water line from the back of the head on the driver's side to the back of the head on the passenger side.

ModularFord has a write up on it. Just make sure to use a metal tee. The plastic t's fail and then things get ugly quickly.

Basiclly there is not enough cooling at the back of the heads and cylinder 8 usually fails. It is worth a look as long as the tranny is out.

Stock Mark stall is 2200.

Test it yourself. Do a light brake stands and see where the tires let go.

ok thanks,

i was misinformed back in december when i did mine,thats why my 2200-2400 i bougt made no improvement,waste of time and money.if only i had known,i just dont want calabrio to be dissapointed,but 2500 should atleast be noticeable.when i first did it,i thought stock was 1600-1800 and my new one was gonna kickass,oh well,live and learn.

if nothing else ,you will have a heavy duty one,thats how i look at my swap.
 
You need a 2800-3000 stall to really notice the difference in a big way. Remember our cars don't start making power until around 3100-3200 rpm.

stall

The stock stall speed is usally around 18 to 1900 sometimes if the converter is worn you can get it to flash higher. But from owning a bunch of mustangs ranging in years from 86 to 99 and most being autos ive found minor work and a 2900 stall speed click real well together. This being my first mark and the car ive wanted since i was 15 i will apply all the mustang tricks and post pics once i start but in your case 2500 will be noticable but not enough.
 
For the record, I didn't expect any major change by virtue of the stall speed-
I expect it to feel like a new car by virtue of having a non-fried T.Converter and a firm shifting healthy transmission.
