I am writing to see if anyone can tell me more about my transmission. I bought a T5 from a 2wd Chevy S10. Near as I can figure it is a 1989 model. There is a tag on it, but it is so thoroughly rusted that nothing can be read on it. Here is a picture: T5 transmission
Here are some other numbers.
The case Basic 4 1352-065-916 cast Aug 88
The lid Basic 2A 1352-097-917 cast Aug 88
The tail housing 1352-066-931
Shifter plate 1352-598-044
Serial number on case CK2106112
I measured and calculated ratios to be:
On a chart Inliners T5 page
I found some numbers. The chart shows ratios of 4.03, 2.37, 1.49, 1.00 and 0.86 for early S10 transmissions.
With the casting dates and the fact that I have an electrical connector for both the backup light and the electronic speedometer, I am guessing that I have a T5 from a 1989 2WD Chevy S10.
There are 2 model numbers that I have found. I think one of these is what was on the rusted tag.
1352-191 is a 1989 GM T-truck 4 cyl
1352-193 is a 1989 GM S-Truck 4 cyl
Can anybody tell me what a T-Truck is vs an S-Truck? Was the T-Truck the S10 Blazer?
I have figured out that it is a NWC (non-world-class) vs a WC (world class) transmission.
I found a table somewhere that listed the gear ratios in a 1989 S-10 and I just can't find it. However, they were completely different than what I have listed above.
Can anyone shed some light on this?
