So, what is a TSB? The letters stand for Technical Service
Bulletin. Every model year Chrysler issued a new Factory
Service Manual, (FSM) but occasionally errors, problems
or updates were needed, so Chrysler issued a TSB for each
situation as required. The TSBs were shipped to dealerships
so that the mechanics and parts guys had the updates. The
TSBs have some information on the right hand border so that
they could be indexed properly. Note the information in
the red box below, we will dissect this information and
it will help us use them.
Note the sequence number, this would have been the 43rd
TSB issued for the 1969 model year which began August 1st,
1968 and ended July 31, 1969. We are dissecting a Plymouth,
Chrysler, Imperial TSB here, Dodge car and truck TSBs would
have their own sequence numbers as well, starting at No.
1. (this changed about half way through the 1971 model year)
Note the date, this TSB was issued on Jan. 13, 1969. Note
the series of numbers below the date as well, the 69 circled
tells us that this TSB is for the 1969 model year. (Some
1969 TSBs were issued in 1968)
Note the second number in this sequence is a 5, this relates
to Chapter 5 of the FSM - Brakes.
The third number in this sequence is a 3, so this is the
3rd revision to Chapter 5 for the 1969 model year.
OK, that was easy, but what if a TSB needed a revision?
Simple, they used the number from the original TSB and added
letters starting with "A" to note that the original TSB
had been updated. If this one needed a second revision later,
it would read 1B.
Now that we have that figured out, you can click the

the TSB indexes for all the TSBs that we have scanned and
made available to use so far.
