In the morning on my way to work... and ive noticed this when the truck hasnt been driven, that when i drive and get to highway speeds the tranny doesnt want to shift into OD i'll be going 60mph at 2700rpm till the tranny warms up and shifts. But when the truck is warm it shifts fine... Im thinkin bout changin the fluid to royal purple hopin that will work. Any thoughts?

 

wont **** into OD? lol jk Joe

 

hahaha i forgot a letter lol

 

Check your fluid.

Trans is flaky with low fluid.


If you want to wake this trans up it needs a shift kit. If you feel like dropping it out a new torque converter makes this a new beast.

 

the fluid is fine... nice and red like it should be.

Where can i find these shift kits? heard about them and was always interested...

 

Are you sure it isn't going into Overdrive, or could the converter just not be locking up?

 

not too sure... like i said it only does it when the truck is cold. i have to really ease off the gas then it shifts.

 

Just to comfort you, mine does it too when cold

 

Ya know I forgot to mention the trans will not shift until it hits 55 degree fluid temp.


For the shift kit there are a few makers. Transgo is the one I have. part number sk55 IIRC.

Bulkpart.com has them.

You will also need upper and lower separtor plate gaskets, low/reverse servo gasket as well as a filter and pan gasket. Plus 8 or so quarts of Merc V.

Your looking at just north of 100 bucks in parts.

You will need a dry warm clean work space. A inch pound torque wrench is a must.

I did not drill my vb as the per trans go kit instructions. It just means if my EPC dies I'm stuck.


Look over at explorer forums 5r55e VB diary for info.

 

5spd FTW lol jk

 

I think it it is tuned to not shift when it is cold to warm up the engine and transmission. Mine does the same thing and I have a shift kit..

 

Crappy slave cylinder FTL lol

 

only manual EVER going in my truck will be a M 1354

Alex you got 32s??? lets see some pics!!
