Low Mount 3800 ALT!

Low mounts in stock today. Newest design has tension belt assembly, cleaned, and blasted. 

Please note.... By the time you get to the bottom of this page, you will be very confused by all the numbers and RPO build codes of these transmissions. No telling what GM changed to make a completely different build code for these transmissions.

Simple thing to remember is the Pontiac Grand Prix GTP has the MN7 98-03 that works extremely well in the Fiero L67/L32 swaps. If you get a transmission of whole engine package from a Buick or Oldsmobile, and it is a L67 from 99-03, you will be getting a 4T65eHD transmission. Ratios are different among the transmissions however. The torque converter is different also.
