has anyone used jegs brand transmissions?

[my86442]

went to buy one and held off when they told me it has no kickdown provision,they block it off for some reason.is there a reason why ? not a huge deal but thinking of getting a tci now,still cheaper than having mine rebuilt.

Most likely for racing. Alot off racers disconnect the linkage to ensure repetative shift times. Instead of winding there engines to the max with the linkage connected between each shift, they disconnect the cable so the shift times are the same most everytime. Just another trick to maintaining constant times and speeds in between each pass. Ive done it.

they bill it as a steet performance trans .will this be hard on it though running it as a summer driver.

I found out the hard way running a 350 turbo without the cable. It burned up everything. The cable is connected to a piston in the trans valvebody that helps regulate fluid pressure in each shift. A few people that i know have modified the piston to allow the pressures to remain so fluid can circulate and keep the transmission from burning the clutchs and bands. the older trannies shift with Fluid pressure. when the pressure gets high or low enough, a valve pertaining to whichever gear in the valve body, opens or closes to allow for the fluid to travel to change the next gear or shift. If they dont run a cable, than they are probably a manual shift valve body trans. Which means you change the shifting times in an auto trans. No this does not hurt the transmission considering its built to shift at your pace. So if you want to drive it everyday, than thats alot of shifting in a auto transmission. If your just gunna weekend warrior the thing than you'll be fine. Im sure theres someone on here that can shed better light on this but thats how i understand this. You can also ask Jegs or summit how these trannys work and they should give you the info too.

The TH350 does NOT need to have the cable connected. All the cable does is kick it down into a lower gear for passing. You will not burn anything up if it isn't there or isn't hooked up.

My86442, your TH350 either failed for a different reason or it wasn't actually a TH350.

It was a th350. If the transmission doesnt need the cable, Why was I told it burnt up because of not having it. I watched the guy rebuilt the entire thing. the only thing he didnt touch was the front pump and the valve body. The car it was in was a 77 Chevelle Malibu with 72,000 original miles. All new clutchs, Bands, drums, planetary, gaskets, seals and filter. it shifted fine after that but I left the cable alone and hooked up. I didnt want that to happen to me again. :?: :?: :? I dont get it. if it wasnt the cable, what could it have been?

One of the things I noticed as well was the difference in the shift times. When the cable wasnt hooked up, It shifted way to soon. By the time I hit 20-25 mph, I was already in 3rd gear. When I hooked it back up after the rebuild, it felt normal as I was in 3rd by 35-40 mph :?: :?: :?:

I've got one. (TH350) It's fun as hell! Puttin a tunnel ram 350 in soon. No Linkage tricks neccesary. I just manual it when it needs to be. There might be an adj modulator, haven't checked.

I've been running my car for two years without a kickdown linkage. i just shift manually all the time. 0 problems. 700r4, yes, you need it. TH350, no. The various engines i've had have always made way more power than required for passing, so i've had no need for passing gear, lol. You'll be fine. People have been removing TH350 kickdown cables for 50 years. It must have burned up for a different reason. Possibly not having the kickdown showed a preexisting condition?

EDIT:

Just had a thought. Maybe your VACUUMN MODULATOR wasn't hooked up? THat's what controls your line pressure.

Manually shifted my old th350 for 10+yrs with cable not hooked up. Cable does nothing but down shift
