Is there a 5 speed transmission for the F-150 that has the bulldog 1st gear AND overdrive also?

Can it be interchanged with a 4 speed?

Does it require a driveshaft change also?

My truck is currently equipped with a 4 speed that has the bulldog 1st gear, and if they are available, I would like to get a 5 speed to replace my existing transmission. I DO NOT want to give up the granny gear though>>>>>>>>>

Has anyone done this? And was it a worth while upgrade?

Thanks in advance for the replies..........

Richmond used to offer a 5 speed that had a 4.41 first gear, but it still has a 1:1 fifth. All that would accomplish is adding a gear in the middle and moving them all closer together. I don't know if the shifter on this trans will work in the trucks. There is also a Richmond 6 speed that has a 3.27 1st and a .76 6th. Of course, neither of these will do you any good over what you've got. Your best bet is probably to get a M5OD and install 3.73 gears. This should get you an overall ratio just a little bit numerically lower than what you've got, plus lower your rpm at 60 mph by around 5%. One of these days I'm going to put a T56 in my truck so I can enjoy the low end of some 4.10's while cruising the highway like I have 2.05's. All it takes is money....

 

Im not shure but i think the only tranny like that for the 150 is the NP-435.

 

Silver Streak, You have said it all....""All it takes is money....""

MEPR...Do you have the NP-435 And what rear axle ratio do you have??

Thanks for the replies....

The ZF used in the late model 250s and 350s will bolt up to your engine. It has a granny 1st and an OD 5th. You'll need to do something about the hydraulic clutch it requires and fab up a chassis mount and shorten the driveshaft.

Alternatively, Advanced Adaptors makes a kit to install a NV4500 5-speed from a late model Dodge 250/350 in a Ford. It's also a Granny 1st OD 5th box. It is a bit more expensive tranny, but the kit fits it to your existing bellhousing so you won't have to mess with the clutch.

 

The ZF S5-42 is about as expensive a transmission as any, ranging from $800-1300 used and even more rebuilt. But it is the only Ford OE manual with a granny 1st and OD. The M5OD's 1st isn't nearly as deep, and it's strictly a light-duty transmission.

 

Steve, try about $900 used, or $1200 rebuilt. These trannys are awesome, but do require a little driveshaft modification. You may also need to modify the t-case shifter, or use one specifically for the ZF. I am hoping to put one behind the 300-6TT I am building. They are pretty close gear ranges, first is something like 5.7:1, versus the ~6.8:1 in the NP-435. Still decently low, and synchro'ed too! This, for me, is a best of both worlds transmission.

 

ftwfred- yeah i have the 435 tranny and my 9" has 3.00s in it. Pulls like nobody business, when it runs. The guy who owned it before me must have hated it, becouse it hasnt been well maintained.

 

Thanks everyone, I'll think I'll look for a NP-435...
I do not want to spend $1200.00 or more for a tranny...
I was hoping I could get one in the $300.00-$500.00 price range.....

Will the NP-435 bolt to my bellhousing?? Can I use my existing driveshaft or do I need to get one from the truck I get the tranny from??

ftwfred-
You may already have the NP435 if you have the granny low 1st in a 4 spd. If it isn't the NP then you may have the BW T18. It is a lot cheaper to get another NP435 than to get any 5 speed that will just drop in.

Mine is a 4 speed. 1st is not synchronized...I was lookin for the 5 speed with granny and Overdrive....

thanks for the replies

The NP 435 is a 4 speed. Your only 5 speed granny/OD options are the ZF and the NV4500 with adaptors. Neither is cheap.

 

Here are the numbers from the tag on my existing transmission

I think the 5 Speed granny/OD Combo may be too pricey for me.............
