stock auto trans build?????

power ranger 2.5 · 07-26-2010, 11:00 PM

does anyone know how to build the stock auto trans to be able to handle the power from 25psi?? i would love to keep my stock trans but i think i might just use a c4 but i cant find a bellhousing for the 2.3 anywhere

I would talk to jess on that one. He has about 25 psi on a stock a4ld, and he did some electric adjustments to it. I would still try to have a C4 built in case of failure, cause for the cost of a rebuilt one you could have one heck of a C4 that won't fail.

for the A4 (a wate of time and money IMHO) you will need the later model internals form a 4.0l Explorer, I am not sure if it has to be the 4x4 one or not....

I have a 2000 4R44E (electronic A4LD). The one upgrade that I had to do and is pretty much a must is the forward planetary gearset. The 2.5 came with fewer planet gears then it's 4.0l counterpart. Also, make sure you have any valve body updates done.

4R44E is the one jess was, is running. adjusting the transmission though the tuner.

thanks for the advice, so all i have to do for the stock auto is change the planetary's, do valve body updates and use the tunner? sounds pretty simple. i just dont want to dump a bunch of money in to the 4R44E if for the same price i can get a c4.

what exatly do i have to do to the valve body?

Don't get me wrong here. A c4 will ultimately be able to handle a lot more then a 4r44e. The c4 has a huge aftermarket behind it. The 4r has virtually nothing. If the 4r isn't shocked to hard, it *should* be able to handle 300+ish horse.... But.....

I recommend that you purchase a 'rebuilt' complete valve body. They are not very expensive and all the homework is done for you. Look at some ford explorer forums for the who what how on the 4r44e/a4ld. It's all been covered quite well.

cool, tanks for the help! i just would rather build stocker (for now). i just didn't know exactly what had to be done to keep it. i seen jess runnin' it and i didnt think it would handle the power or if it was very practicale. i don't plan on making to much power (untill i get more money).im just going to start out with 10 or 12 psi and work my way up from there.so the 4r44e will work for me for a while.
