I am going to order a set of shift pins from BMW (about ~$30 of parts) to see if there is a difference between shift pin (specifically, the diameters) item 28 and 26.

26 is the spring. I ordered three sets of 28 (048). My guess is all three use the bushing.

048 retails for $10.10 each now.

 

26 is the spring.

You are right. I posted too fast.

 

I bought all the parts & tools to do Daniel's (and one other car; both mine were done by Yark), but we haven't gotten around to it yet.

Daniel gave me the part numbers based on TIS/SEB info, but there weren't enough pin sets, so I ordered four (4) more sets.

 

I bought all the parts & tools to do Daniel's (and one other car

I have the parts and tools but no car to put them in.

 

I ordered and finally received part 28 and part 27 from BMW.

Both were backordered. 28 is the 048 part number kit of 3 parts that Ron shows. 27 is a pin by itself, but it is a different size pin than the one that comes in the kit of 3.

The outside diameter of 27 is about the same size as the OD of the bushing included in 28. At least from BMW's EPC, it appears 27 does not use a bushing.

Ron's guess is that all 3 shift pins use the bushing, but I don't think we will know for sure until someone gets in there. You would certainly think that the shift pins that use bushings work better than the ones without. There is some kind of coating on the ID of the bushing.

 

Maybe that's the upgrade; switch over the non bushing plungers to bushing ones?

We still haven't done Daniel's yet. In fact, we haven't seen him since the last time we saw you & Ron (and about another thousand Z owners).

 

I ordered the pins a while back. I plan on a group of items when its time for a clutch, lightweight flywheel, shift pins, shift linkage bushings etc., guibo, and possibly a few other things.

I will have to look if I bought bushings for all the pins. I also bought the tools to remove the pins. there were several if I remember correctly.

 

Could someone please post the TSB number for the shift pin fix and perhaps the contents of the TSB?

SITUATION:
Increased effort is required to engage and/or disengage gears with transmission at operating temperature. Please refer to SIB23 01 99 when diagnosing shifting concerns.

CAUSE:
Shifting pin sticks in bore.

CORRECTION:
On a customer basis, replace catch pins for 1st/2nd, 3rd/4th, 5th/reverse gears.

PROCEDURE:
Refer to BMW repair instructions 23 30... Note: This repair procedure can be accessed by entering the repair instruction number, or proceeding to repair group 23, subgroup 11 of the appropriate series. The transmission must be removed to replace the catch pins. BMW Special Tool 23 3 110 is necessary to perform this procedure, and will be distributed to all BMW centers via automatic tool shipment.

Under no circumstances should both labor operation numbers be claimed. Attempts to claim both times will result in an unnecessary delay in claim processing and payment.

I had the pins changed out under warranty and the shifting improved noticeably.

 

Jon, Did you ever do this procedure? Any tips or info on your findings? Is there a 100% answer on if the trans has to come out or not?

One hundred percent (100%) yes.
