Jegs 350t trans..... No good!!!!!!

Hey everyone

I just wanted to tell you guys i went to Jegs over the weekend and spent over $1100 bucks,, I bought A Jegs brand 350t trans and also with that i got a new trans cooler with a fan and all the nice AN fittings w/ braided hose just because i wanted to do everything right u know...

Ok for the price of a Jegs brand trans i really shouldn't be upset, it is only $629+tax But here is the thing there trans are supposed to shift hard and firm for any car with around 400-450hp NOT!!!!! I just got done putting that thing in my car and i dont think it is going to be worth a crap!!! The trans i took out of there had at-least 100,000 miles on it and i think it shifts harder than the new Jegs 350t??
I just wanted a harder shift so i called jegs and was talking to a few of the guys that worked there and they said there trans was really built by B&M but was $200 cheaper and shifted just as hard, so i figured it was a good deal since shops wanted $500 just to rebuild mine u know...... well i guess the guys at jegs lied lol

Has anyone else bought a jegs trans and had any good or bad luck???????

what type of fluid did you use in it ? B&M recommends B&M Trick Shift or Type F for any trans with a B&M shift kit in it.

if you used Dexron III, thats why youre not feeling the punch.

Calibrating shifts is not done with fluid...
Why use an inferior fluid?
Use Dexron and install a valve body kit.

Sometimes it takes a while for a trans. to really "break-in". Take it easy for a while and put some miles on it, then start giving it some W.O.T. runs and see how hard and firm the shifts are. I have heard lots of good feedback from customers of B&M transmissions, so they do know their stuff most of the time, I suppose you could pick up a bad apple from them though once in awhile. It has happened many a times before and I am sure it will happen again!

My understanding from books on rebuilding TH350's and from people that rebuilt these was that Type F has a different friction modifier and will make the shifts harsher as it doesn't slip as much. Definately not the same as messing with the valve body, but it will create a difference.

Was it the converter in the 100K unit you took out? If not, what did the 100K unit have for a converter?

Type F will make a slightly firmer shift, it has NO friction modifiers according to my literature.
It has a significantly lower heat resistance than Dexron.
IMO not worth messing with, it is also getting harder to find.

I would buy a valve body kit and install that and be done with it.

I would call Jegs and/or B&M and ask them if the trans you bought has their shift kit installed in it. If yes, then you may have a bad unit. If no, I would ask "why not"?

I have a Turbo 350 in my car - a very old one with over 100,000 miles on it and a stock torque converter with over 100,000 miles on it. the trans shifted very softly when I got it. After installing one of the B&M shift improver kits in there, it now shifts very quickly, and firm. It even screeches the tires when shifting from 1st to 2nd. I am running the type "F" fluid, not the B&M trick shift fluid. It took approximately a total of 3-4 hours to complete the (very messy) job and about $50 for the kit. Well worth it.

Like I said, ask Jegs and B&M if the trans you bought has the shift improved kit installed in there.

Hey guys,,,I just got done adjusting the mod and it seems to of help it a little but to be honest for a $700 trans i would think it would shift little harder then what it is doing.... its not slipping or nothing but just not hard at all,,, of course having a big stall will make a trans feel like its not shifting really hard but firm u know... I have only had 1 trans that chirped the tires when having a big stall in it, but all of the trans i have had w/shift kits and big stall's shifted hard enough to feel/jerk you a little bit BUT this jegs trans just shifts firm, really cant feel it shift? like i said before ill give it a week and if its not going to get better ill take it back ,,,,,, And yes it does have a B&M kit in it
