transmission qustions

Hello every one I am just starting my cj-5 project and It has a t-90 in it and the 302 blow 2ed gear so one the first question
is what kind of transmission would you recommend? My thought is to look for a t18 for the ford motor.

Second. would u recommend a used transmission and if so what precautions would u recommend?
Thanks every onefor ur help
Joe
Eh

Isn't the T18 THEE transmission of All transmissions. Doesn't it have something like a 7.0 first gear? That has been my dream transmission since day one. I did see some rebuilt models at my local 4x4 store Oly4x4.com and IIRC they were $1200.

If it were me I would get a nice rebuilt model, that way you can kinda be one and done, and probably not have to repair it for a while. The other option would be a TH400 or TH350. New they are around 2200 IIRC. Not sure if you wanted to go the AT route though.

A T18,T18A or T19 will hold up to 302 power. Look at Fords,Jeeps and Scouts.

Since you haven't filled out your profile, I'll assume you're running an early CJ (pre 71).
What transmission you want is based solely on what you are doing with the rig. You won't be happy with the T18 if you're hotrodding or street driving. The 150 or 176 would be a better choice and should mate nicely to your Ford engine.
I would visit the Novak website and look at both what transmissions are available as well as the cost to adapt them. don't forget that the drivelines will probably have to be reworked as well.

Scout t 18's are different. the bell housing and input shaft are different, but most mate up to a dana 20 so you can use the output shaft and factory adapter with the ford t18 tranny.

I don't know about it being THE transmission, I went to Novak and read a bit about the transmissions they had listed my thought was that its a strong 4 speed that I should be able to bolt up to my 302. I'm going to do a ground up on my jeep an was thinking of getting a used one to start and rebuilding that with at the same time as the motor because the hole thing has been sitting for 10-12 yrs

I am doing a 1960 Willys with a 1980-85 302 ford the person that did the swap left the t90 in and it blow out 2ed gear and I want a transmission that will hold up to the power and that will be very reliable.

I was planing on the t150 at first but I found the Novak website and from what I read the t18 sounded the best option because it should bolt up to the motor and sounded very strong

Gear wise it is one of the lowest, no? And it is short IIRC, and should be plenty strong. That's what was behind my reasoning.

Well I didn't realize it was so highly regarded from what I have read its a great one and with the info you have given me I am more convinced its the best choice for what I want. I do have one more question would the t18 be able to hold free way speed 75ish?

Just looking at the numbers the t18 has a 4th gear of 1.0 and the ax-15 has a 5th gear of .79 so you would loose a little bit there. What I would do is just calculate the acceptable RPM's at 75 and see if the tire, gear, trans, engine combo looks good in that range. My gut tells me that this set up is going to be more comfortable in the 60mph range than the 75mph range. Hopefully someone that has done this swap can chime in.

The T90 and the T18 both have the same gear ratio in high, so your road speed will be the same.
If you want to run 75MPH, you picked the wrong platform. The wheelbase is too short, the brakes are marginal at 50, and the stock steering is horrible.

^^^yes it would be a little scary. No need to go that fast in a jeep man, too dangerous. If people want to pile up behind you in the slow lane, let them. I don't let people 'PUSH' me down the road, I will go 60mph MAX with my current setup.

I have a t18 in my cj. I havent tried 75 mph, I normally stay under that. If you dont do any rock crawling you probably dont need it. I normally start out in 2nd gear.

Not sure about the ford T-18, but the jeep T-18 comes in two different gear setups. Not sure the exact ratio but one has the 6.8? low first gear, the other has a 4.?? first gear. I had the 4.?? In my old CJ and it was great for the street. Make sure you get the one you want.
