Colin has a TH 350 trans for his project and i was wondering about the differences between the older kickdown cable style trans and the newer TH 350 without a kickdown cable. 1st, Is it a TH 350? 2nd, Will this newer type of trans work without a computer? 3rd, To make it function correctly, will it need modifications for an electric kickdown? 4th, Will it also need modifications to engage the lockup torque converter? Or is it a "No-Go" for this type of tranny? Any and all help will be apreceated. Thanks...

i beleive all turbo 350 came with a cable kick down. does it have the same pan shape as th 350? if you can draw up a picture or take a pictue of the pan and post it on here maybe someone can id it.i beleive there is a web site that can show the diferent pan shapes. i`ll dig out my tranny book and see if it says any thing about an electric kick down. th400 have an electric kick down .

I haven't looked at it in great detail but i only concerned myself with the bolt pattern and the fact that it didn't have a cable or a provision in the casing for one. It also has a 4 pin connector just below the shift linkage. I'll have to get some more info from Colin and get back with you. Thanks..

if it is a newer trans he can still use it .he can order a kit through one of the performance companies that allows the converter to lock up. i think you have to flip a toggle switch off and on to make it work when you need it to which is only when in o.d.

it could be a 200r4 i dont think they had the cable and they have both bolt patterns in the bellhousing if that's what it is they get 250$ just for a core before the rebuild they came in the Buick Grand Nat and some caddy 's and olds

This tranny has both bolt patterns, it has some kind of spring loaded item in place where the kickdown cable would go. The pan is square except for one corner( its got a 45 degree wall in relation to the pan. 250, 350, 375B) And i think it has the letters MX on the bell housing near the dipstick tube(big letters). And the 4 pin connector(pointing up) just aft of the shift lever. If i remember correctly, some trannys had "metric" stamped on the oil pan. This trans did not! It has a vacuum modulator. The eng / trans came from a mid-80s Buick. if you need any specific info, let me know and i'll look for it. Thanks

If you have a modulator valve it is either a Turbo 350 or a 250. The 250 was similar to the 350 except it uses only a band for 2nd and will have a adjusment nut on the side of the case toward the front about half way up the trans. I only saw a few 250's but they were used in the mid 80's. I don't remember seeing one that was a multicase.
All 350's have kickdown cables and modulator valve. None of the 200's,700's,or 2004R use a modulator valve they are controled by the TV (throttle valve) cable. 350 mod.valve points to the rear and is at the rear of the trans and 400 points to the passenger side and is at the front of the trans.and has no cable.

This trans has the mod-valve located passenger side, near the tail, pointing straight back. A hole where the kickdown cable should be but it has a spring loaded item in place for the cable. Should he go out and get a cable assy and install it? Right now with the 4.56 gearing, it really wouldn't come into play but will he need it anyway for the trans to function correctly?

The cable is not a big deal and it can be used without one as long as the hole is not going to leak fluid. You will notice if you take off hard it will shift too quick and it won't kick down but in normal driving it is fine. The cable hooks to a wire like linkage that will be spring loaded is that what you are seeing? They have cable's that are universal and cable brackets are at Advance and Auto Zone so it would be easy to hook it up.

It sounds like the trans will work ok for what Colin needs for now. thanks for the help...John

The kickdown on my th350 was spring loaded i think and it sounds like yours is the same.

I talked to 2 different tranny shops and they both said it has to have a cable if its a 350. So i took the item off of the trans to see what the hell was going on! Lo and behold! The kickdown rod that attaches to the valve body was there! The prevoius owner made a very elaborate cap to seal off the trans. I dont know why they would have needed to do such a thing!? The donor was a 83 Regal. Anyway, that mystery is solved and now i can concentrate on the lock-up torque converter. I've looked thru Jegs and Summit but they didn't list a 350 kit that i could see.

the 350 doesn`t use a lock up converter.or were you talking about trans kit?

It must be a 350. It's identical to mine(it has a kickdown cable end that wont be used for now) but it has that 4 pin connector just aft of the gear selector(the plug only uses 2 wires). The kit i'm looking for is to engage the lockup converter. the local tranny shops confirmed that it's a 350 and if i dont run with a lockup, it will cause the trans to overheat. They called it a TCC.

Some TH350's did have a lockup for fuel mileage. I don't think it will overheat cause it doesn't have overdrive, but i'm not sure on those. U have to have lockup for an overdrive trans or it WILL burn up your converter. for the TCC (torque converter clutch) u can use the B&M lockup kit, but it costs about $160 from summit. pn# BMM-70244 OR BMM-70248 (depends on whether u have a mechanical speedo or electrical).
