Self Transmission Installation
Hi I was told I should get a new transmission a year ago and recently I have gotten into working on my car so I was thinking about my next project and thought perhaps I should tackle what ought to have been done a while ago. I Had a new engine put in a few years back but left the Transmission in as is because I ran out of money. I want to ask if I would be able to replace the transimission myself and whether i should buy a brandnew transmission or rebuild the old one. I can still drive the rig but I am starting to feel the shifting getting progressively sloppier. Thank you for anyhelp.

If you read up and rent trans jack you should be fine . You will need several long socket extentions and a universal of them.
remove shafts
remove wires
support trans and xfer case
loosen tranfer to trans bolts
remove cross member
remove xfer (with jack )drain it you'll have fluid all over if not.
remove starter
Remove all trans bolts and linkages.
The pan covering tork converter.
four bolts on fly wheel
You can pop top manifold it will make life so much easier. You can get at 2 top bolts easier. I have done this with out dropping y-pipe but it give more room. If you are on your back and just jacking truck up . Take trans and xfer apart They are heavy and you will have to have truck way higher to get out in one piece. you will need new seal between Trans -xfer and rear out put shaft seal on x-fer. Good time to do rear seal if needed, check egr tube as its easy to get at with out trans in way, and trans/xfer mount. I'm sure i missed something Good luck

For safety reasons never work under a truck alone. I replaced my trans on my 82 Bronco and always had someone at least there to hand me tools. A trans jack is a good idea but if the trans becomes unbalanced and falls on you it break your ribbs or arm.Had a guy here not too long ago died working on his truck alone when for some reason it rolled bck on him. Not preaching just dont want anyone hurt.

Agree - never work alone..
But to make life a bit easier when installing the transmission... Take 2 transmission bolts - get identical cheap replacement bolts - Cut the bolt head off - then file two flat spots where the bolt head was so you can get on it with a 3/8" wrench.
Install these two "Guide" pins into the middle center two holes - This will make lining up the Tranny much easier... OBVIOUSLY be careful and ensure you support the tranny the whole time (Tranny jack) otherwise you will crack the tranny housing and be screwed... Once you BOLT the 4 bolts in, use the 3/8" open ended wrench to remove the pins and replace with Tranny bolts..

Your post didnt say how many miles or how hard they were put on the tranny. My suggestion is that be sure of your tranny man and his advise. I have salvaged many good miles from trannys that "needed to be rebuilt". My experience is that the tranny filter and valve bodys (at least on mine) are generally the problems.
My 93 351 with E40D shifted like my 93 yr old mother walks-----that is very slow!! I cleaned the VB sections and put a Baumann shift kit in it set to "Medium" on all settings. Also replaced the filter. Added new V oil and it has done great ever since. Well-----almost! I later had to replace the TC because of slippage and overheating, so while you are in there, replace yours if it dosnt have "luk" clutches. Still shifts great at 140K and I am not an easy driver.
