Transmission number Identification

[Jeeper42]

Hey Guys,

I'm trying to ID my Transmission so I can get a new 2nd gear synchronizer.
The teeth on mine are shot.

I have a 1986 CJ7 5 Speed M/T

The only numbers I found were:

sf8950010 and 2 unknown numbers.
13-52-dn 45684

But I can't find reference to any of these.

Or maybe it doesn't matter as there isn't more than once type of synchronizer for my Transmission .

Anyone have a good source for Transmission parts?

Thanks,
Jeeper42

Probably a T-5 .


T-5
Five Speed
From 1982 to 1986 the Borg-Warner T-5 was offered in CJ's as as Overdrive Transmission . As a matter of fact this was the only Overdrive Transmission offered in a CJ. The T-5 is a light duty Transmission that always came with a Dana 300 Transfer Case .
There was a heavier duty T-5 Transmission that was used in street vehicles such as Mustangs. These transmissions were referred to as World Class T-5 . They were never offered in Jeeps or any other four-wheel drive but there are companies such as Astro Performance that offer the gears and parts to rebuild the T-5 into a World Class T-5 . The strength of these transmissions is not as strong as originally hyped and it isn't recommended to rebuild your T-5 into a World Class T-5 . A better option would be to replace the T-5 with a stronger Transmission such as the T-176 or T-18 .

The T-5 is 15.25 inches long.

For more information see the above post Weak Transmissions of the 1980's

Gear ratios:
1st – 4.03
2nd – 2.37
3rd – 1.5
4th – 1.0
5th – 0.86
Reverse – 3.76

Well then it looks like I have a T-5 but now I'm having issues finding a 2nd gear synchronizer.
My brother-in-law who is rebuilding the Transmission said I need a new 2nd gear synchronizer but all I can find are ones for 1st & reverse, 3rd & 4th and 5th.

He told me the teeth are warn down and it keeps popping out if second.

Is there a synchronizer for 2nd gear?

Are we talking about #98 in the pic? Look at this link. Ignore the WC T-5 . Scroll down for Jeep T-5 and down further for the diagram.

The synchro hub and sliding synchro sleeve are only serviced as part of the mainshaft ( from Jeep anyways).
2nd gear and the synchro rings are available seperately according to my books.
