Shifter stops needed?

the stops are not needed. in fact tremec highly recomends you don't use them. but if you want too use them make sure you have a little bit of a gap when holding the shifter into all gears. you don't want the stops stopping the handle before it is fully engaged in gear. this can cause the trans too pop out of gear and this WILL bend the shift forks.

when we installed my short throw we put the stops far back and made sure they couldn't be hit no matter what. like mike said, its recommended to leave them out, but if you leave them in make sure they're not going to hit

I took mine out also. I don't slam my gears so I am not really concerned.

"NOTE:From Tremec dated 03/01

Tremec Transmissions
Service Bulletin 03.01


Subject:
Aftermarket Shifter Stops

Transmission Models Affected:
All
Severe damage may be caused by installing an aftermarket shifter with "shift stops" on any TREMEC transmission. All TREMEC transmissions are designed and manufactured with built-in shift stops to prevent over shifting. Therefore; shift stops on aftermarket shifters are totally unnecessary when used on a TREMEC transmission. TREMEC "TR series" transmissions have multiple shift rails with shift stops on the gearing. TREMEC "T series" transmissions have a single shift rail system with stops built into the guide plate.

When installing an aftermarket shifter on a TREMEC transmission it is best to remove the shift stops to avoid miss adjustment, and the potential of the screws vibrating lose. A misadjusted shift stop can cause an under-shift, which may lead to a gear jump-out situation. If the transmission jumps out of gear, the shift fork can be bent causing permanent damage to the transmission. Shift forks can also be damaged by "clash shifting". A clash is caused by a missed shift.

Neither an "under-shift", nor a "clash shift" can be prevented by shift stops. TREMEC shift forks are designed to take loads up to ,000 lbs. However, a gear jump-out may well exceed 1,000 lbs. of force, which may result in a permanently damaged transmission."

In lieu of the post above I would like to state I am not in total agreement with what Tremec is saying. I beleive the reason for their caution is the fact that so many of the aftermarket shifters are mis-adjusted and do cause problems with their transmissions so they feel it best for them to be left out.

I can't seem to remember inside the 3650 there even being a shift stop on the 3-4 gate assembly, only on the 1-2 gate assembly and 5th gear shift fork. That said, even if there was a stop on all of the gears what is stopping the extra pressure that is being applied to the shifter turret assembly and the nylon piece mounted on the shifter ball that is inserted into the socket of the main shift selector rail? What about the pressures that are applied to the selector arm which determines which shift rail is selected? These are all before the stops used in the 1-2 gate and 5th shift fork.

I use the stops and I make sure they are adjusted properly like the Shifter Manufacturer's are instructing the installer to do. I use a .010" gap gauge for setting mine up, by putting force againt the shifter towards the 1-3-5 direction and adjusting to a slip fit gap of the .010" gauge and then doing the same on the 2-4-R side. I always make sure I use locktite on the stop bolts and the stop bolt lock nuts to ensure that nothing will move and become mis-adjusted from viabrations.

I do bang the gears hard sometimes and the amount of flex that is applied during those shifts will flex the internal parts enough to allow the .010" gap adjusted into the shifter to be used up and hit the stops on the shifter assembly. If one never plans to speed or power shift would be the only reason that I could see for leaving the stops out of the aftermarket shifters.

I know all about that huh mike? Bent shift forks = an embarrassing poping out of second constantly!

I removed them on mine. The instructions for my MGW told me to leave them out for the 3650.

I am courious to as why they would provide stops on the 3650 specific shifter if they were not required? Seems to me they would not manufacture them into it if the need was not there.

The instructions said you could use the shift stops at your own risk if you wanted to but you don't need them.

I left mine out also.

I don't believe Ford/Tremec saw fit to add shift stops to the factory shifter, correct?
